Abstract ：
The settlement formula for pile-supported reinforced embankment is established by improving the elastic foundation beam method and combining the column unit method. The traditional Winkler beams is replaced by the Timoshenko beams, and the constraint of the height of fill can be neglected because the lateral friction on the pile side is considered in the column unit method. The presented method is employed to analyze a practical engineering and compared with other methods. The results are shown to be reasonable. The effects of the variation of parameters such as pile spacing (s), thickness of load transfer platform (LTP) (h) and tensile stiffness of the geosynthetic (S-r) on the pile lateral friction and the settlement of pile-supported reinforced embankment are investigated. As s/d increases, the elastic zone with lateral friction resistance becomes shorter and shorter. The plastic zones at both ends become longer and longer. The maximum settlement generally increases with the increase of s/d. When s/d <= 4, the maximum settlement increases little, but when s/d > 4, the maximum settlement increases large, and the rate is 4 similar to 5 times of s/d <= 4. With the increase of h/s, the length of elastic zone due to pile side friction changes little, but the whole zone shifts upwards. The maximum settlement shows an obvious gradient increase. When h/s = 0.5 the maximum settlement is about 1.5 times of h/s = 0.3 maximum settlement. With the increase of S-r, the whole elastic zone of pile side resistance becomes shorter and shifts upwards. The maximum settlement decreases in a gradient way. The settlement at S-r = 4000 is about 0.75 times of that at S-r = 1000. This paper expands the settlement theory of reinforced embankment and is closer to the real conditions, which has certain scientific significance and application value.

Abstract ：
The limit failure modes and earth pressure distribution of excavation retaining structures under rotating about the top (RT) displacement mode were systematically investigated. Finite element limit analysis incorporating the HMC constitutive model was employed, leading to the establishment of a logarithmic spiral failure surface model that accurately characterizes curved slip surfaces, overcoming the limitations of conventional Coulomb failure surface assumptions. An asymmetric soil arching effect characterized by a distinctive arch feet difference (Delta h) was identified. An optimized arch-shaped differential element method was developed, in which asymmetric arch-shaped differential elements were established along the principal stress rotation trajectory at the soil's limit state. Analytical expressions for earth pressure were subsequently derived based on their mechanical equilibrium equations. Systematic parametric studies were conducted to quantitatively analyze the influence of soil properties, interface friction angle, and surface surcharge on earth pressure distribution, resultant force, and its point of application. These combined advances establish a refined theoretical framework for earth pressure calculation, offering engineers improved design accuracy for excavation retaining structures.

Abstract ：
The trapdoor test has been widely used to study engineering scenarios where pressure calculation methods need to be re-evaluated due to relative soil displacements. To propose a more reasonable calculation theory, over the past few decades, researchers have primarily focused on understanding soil deformation mechanisms and stress evolution on the surface of the trapdoor. However, the limited availability of experimental data has hindered the development of a universally accepted theory. In contrast, FEMs offer a powerful tool for capturing more comprehensive and precise stress-strain information. In this study, various active trapdoor models were established, each with a width of 2 m and differing burial depths, using the FEM. By integrating the ground reaction curve, the normalized stress distribution on the trapdoor was analyzed to reveal significant stages in soil stress evolution. Additionally, the Mohr-Coulomb failure criterion was applied to differentiate between sliding and failure surfaces, shedding light on the evolution trend of the failure surface. Moreover, three lines and four points were selected to monitor the evolution of principal stresses in the soil. Drawing on principles of plane strain mechanics, the distributions and evolutions of the three principal stresses were presented in the xy-plane using vector graphics. Notably, this study highlights the crucial role of the intermediate principal stress in soil arch calculation theory.

Abstract ：
This study develops an analytical model to determine the settlement of a composite system involving a pavement structure resting on a geosynthetic-reinforced embankment overlying voids. In the model, the pavement structure is postulated as an Euler-Bernoulli beam on a continuous elastic foundation, and the geosynthetic-reinforced embankment is idealized as an Euler-Bernoulli beam spanning voids. The Winkler foundation model is revised to simulate the absence of the voids under the geosynthetic-reinforced layer, and the corresponding equations and solutions for the composite system subjected to uniform loading are derived. The proposed solution is validated against the existing theoretical methods of a dual-beam on a continuous foundation without voids. The results indicate that the existence of underlying voids has a great impact on the settlements of a composite system involving a pavement structure resting on a geosynthetic-reinforced embankment. The proposed analytical model can provide a theoretical insight into a preliminary design of a geosynthetic-reinforced embankment overlying voids.

Abstract ：
This study conducted model tests to simulate the passive failure of granular soils under different displacement modes, including the translational and rotation modes concerning different pivot points, to investigate the effect of displacement modes on the failure mechanisms and earth pressure. Experimental results were compared with the finite element limit analysis (FELA) method and theoretical solutions. Test results show that a composite log-spiral shear band formed under the translational mode, whereas a single log-spiral shear band can be observed under the rotation mode around the top. Furthermore, the failure mechanism of the rotation mode around the midpoint involved wedge-type and rotation-type flow zones induced by the combined active unloading and passive loading. Given a lower pivot point, the required wall rotation for the soils reaching the passive limit state increases. Earth pressure distribution varies across displacement modes: in the translational mode, earth pressure increases uniformly with depth, whereas rotational modes show nonlinear distributions. Classical earth pressure theories are only applicable to the translational mode and tend to overestimate passive earth pressure in rotational modes. The experimental results provide a valuable benchmark for validating numerical simulations of passive failure, and charts of passive earth pressure coefficients considering displacement modes are presented for the design of rigid retaining structures.

Abstract ：
A cantilever retaining wall that includes a relief shelf represents a unique embodiment within the realm of retaining walls. Semi-infinite non-cohesive soil’s translational mode failure mechanism can be probed utilizing the adaptive finite element elastoplastic analysis (AFEEA). This methodology indicates that such walls exhibit dual failure surfaces, one originating at the wall heel and another at the shelf’s end when the shelf is sufficiently extended. To summarize, comprehension of the interrelation can be achieved by classifying walls into those with long and short relief shelves. This study applied equilibrium limit analysis on the horizontal differential layer to determine the active earth pressure of cantilever retaining walls with the relief shelf in semi-infinite non-cohesive backfilled soil. The investigation of four key parameters—relief shelf length, position, wall heel length, and soil internal friction angle—highlights their significant roles in altering active earth pressure. As a result, when the relief shelf aligns at 0.4 times the wall’s height from its pinnacle, it presents minimal total active earth pressure (Ea). The conclusion drawn is that within a specific range: The active earth pressure decreases as the length of the relief shelf increases and the length of the wall heel decreases. © The Author(s), under exclusive licence to Indian Geotechnical Society 2024.

Abstract ：
Cantilever retaining walls are commonly used due to their lightweight and self-stabilized soil mass above base slabs. Although several studies have extended earth pressure theories for cantilever retaining walls, these theories have limited applicability to further predicting the stability against cantilever retaining walls. In this study, the finite element limit analysis method is verified through comparisons with existing experimental tests, and then a comprehensive numerical model for the stability of cantilever retaining walls is established. The model combines the finite element limit analysis method with the strength reduction method to cover most practical project situations. Compared with the limit equilibrium method, the finite element limit analysis model provided a prediction of the safety factor based on the most probable failure mechanism considering soil properties, wall geometries, and interface properties. Furthermore, a series of parameter studies are conducted to investigate the effect of various parameters on the stability of cantilever retaining walls. Based on a large dataset obtained from the model, a neural network model is trained and validated to provide a surrogate model for a convenient prediction of the stability of cantilever retaining walls. © 2025

Abstract ：
The load transfer mechanism and failure mode of narrow soils induced by rotating about the top of excavation retaining structures (RT displacement mode) are investigated using the Finite Element Limit Analysis (FELA) method with the Hardening Mohr-Coulomb (HMC) model. A logarithmic spiral curve model is innovatively proposed to accurately characterize the evolution of the failure surface in narrow soils behind retaining structures under RT displacement mode based on numerical simulation results. Through analysis of principal stress vector diagrams obtained from FELA simulations, an asymmetric soil arching effect is identified in the upper zone of the narrow soils behind the retaining structure. An optimized differential element method is developed by constructing asymmetric arched differential elements along the deflection of principal stresses at the soil's limit state, thereby establishing an analytical framework for calculating earth pressure in narrow soils under RT displacement mode. The proposed analytical method is validated through favorable agreement with finite element analysis results. Additionally, sensitivity analyses are performed to evaluate the effects of soil strength parameters, interface friction angles, and aspect ratios on earth pressure distribution, earth pressure coefficients, and the location of the resultant thrust. © 2025 Elsevier Ltd

Abstract ：
Over-break and under-break excavation is very common in practical tunnel engineering with asymmetrical cavity contour, while existing conformal mapping schemes of complex variable method generally focus on tunnelling with theoretical and symmetrical cavity contour. Besides, the solution strategies of existing conformal mapping schemes for non-circular tunnel generally apply optimization theory and are thereby mathematically complicated. This paper proposes a new bidirectional conformal mapping for over-break and under-break tunnels of asymmetrical contours by incorporating Charge Simulation Method, which only involves a pair of forward and backward linear systems, and is therefore logically straightforward, computationally efficient and practically easy in coding. New numerical strategies are developed to deal with possible sharp corners of cavity by small arc simulation and densified collocation points. Several numerical examples are presented to illustrate the geometrical usage of the new bidirectional conformal mapping. Furthermore, the new bidirectional conformal mapping is embedded into two complex variable solutions of under-break shallow tunnelling in gravitational geomaterial with reasonable far-field displacement. The respective result comparisons with finite element solution and existing analytical solution show good agreements, indicating that the new bidirectional conformal mapping would extend the mechanical application range of the complex variable method in practical over-break and under-break tunnelling.

Abstract ：
Over-/under-break excavation is a common phenomenon in shallow tunnelling, which is nonetheless not generally considered in existing complex variable solutions. In this paper, a new equilibrium mechanical model on over-/under-break shallow tunnelling in gravitational geomaterial is established by fixing far-field ground surface to form a corresponding mixed boundary problem. With integration of a newly proposed bidirectional composite conformal mapping using Charge Simulation Method, a complex variable solution of infinite complex potential series is subsequently derived using analytic continuation to transform the mixed boundaries into a homogenerous Riemann-Hilbert problem, which is iteratively solved to obtain the stress and displacement in geomaterial. The infinite complex potential series of the complex variable solution are truncated to obtain numerical results, which is rectified by Lanczos filtering to reduce the oscillation of Gibbs phenomena. The bidirectional conformal mapping is discussed and validated via several numerical cases, and the subsequent complex variable solution is verified by examining the Lanczos filtering and solution convergence, and comparing with corresponding finite element solution and existing analytical solutions. Parametric investigation is conducted to illustrate possible usage of the proposed analytical solution. Further discussions are made to disclose possible defects of the proposed solution for objectivity.
