Abstract ：
Freeze-thaw processes can cause slope instability in areas with short-term frozen (STF) soil, resulting in potential safety risks and huge financial losses to a certain extent, as these processes affect the physical and mechanical properties of the soil. However, their adverse effect on the mesoscopic-level mechanical properties of residual soil has not been adequately investigated. To gain an effective understanding in this regard, a laminated-wall approach was adopted to create a flexible boundary for a triaxial-shear test. Simulated stress-strain curves closely matched experimental results, with a maximum relative error of 7.81% at the peak. Moreover, the experimental data collected from real soil subjected to freeze-thaw cycles were used to calibrate the relation between the macroscopic and mesoscopic parameters. The deterioration of the macromechanical and micromechanical parameters of residual soil primarily occurred in the first four freeze-thaw cycles. For eight freeze-thaw cycles, the damage degree of each microparameter remained the same, reaching approximately 0.37. A freeze-thaw damage model of the mesoscopic parameters of residual soil was then constructed through parameter fitting. Using this model, the impact of frost-thaw on slope deformation behaviors was analyzed. A simulation revealed that displacement primarily occurred at the slope toe and the area of influence expanded with an increasing number of freeze-thaw cycles. As freeze-thaw cycles increased, the stress distribution in the X-direction along the top and surface of a slope became more concentrated, impacting mesoscopic parameters. Conversely, the stress in the Z-direction on the slope dispersed across three slopes after four to eight freeze-thaw cycles, with considerable influence during the initial four cycles. The flexible boundary created using the laminated-wall approach and the freeze-thaw damage model of the mesoscopic parameters facilitated an effective understanding of the freeze-thaw effect on residual soil obtained from an STF area.

Abstract ：
To reduce the consumption of Ordinary Portland Cement (OPC) in subgrade reinforcement, steel slag (SS) and calcium carbide residual (CCR) were applied to solidify undesirable soil. The relationship between the unconfined compressive strength of solidified soil and OPC, SS, CCR was analysed by response surface method. The result showed that SS and CCR exhibited synergistic enhancement on the strength of solidified soil. Compared with OPC solidified soil, the introduction of 11 % SS and 6.5 % CCR could reduce 4 % OPC at the same strength. OPC/SS/CCR solidified soil could reduce cement consumption and recycle industrial solid wastes, which was conducive to reducing carbon emissions and protecting ecological environment. Then, the interaction mechanism of SS and CCR on the strength of solidified soil was thoroughly investigated by crystal structure, chemical composition and micro-structural morphology. CCR increased the alkalinity of soil and SS provided silica-aluminum oxides, these two solid wastes synergistically promoted the hydration reaction. Compared with original and OPC solidified soil, newly produced AFt (3CaOAl2O33CaSO(4)32 H2O), more C-S-H (CaOSiO22 H2O) and calcite were found in OPC/SS/CCR solidified soil. These hydration products could fill the deleterious (extra-large pores (>20 mu m) and large pores (5-20 mu m)) in soil, reduce the porosity and enhance the compactness, which achieved a significant increase in the strength of solidified soil.

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 ：
To promote the anti-ageing performance of asphalt, layered double hydroxides (LDHs) modified by propyl trimethoxylsilane (MPMS) was prepared and applied to modify asphalt. Fourier transform infrared spectroscopy (FTIR) showed that MPMS was chemically-grafted on the surface of LDHs. The interaction between LDHs and asphalt was significantly enhanced after MPMS organic modification, and MPMS organic LDHs (OMLDHs) exhibited better compatibility in asphalt. OMLDHs and LDHs could enhance the high-temperature properties of asphalt, particularly OMLDHs. After ageing, the properties and structure of asphalt were dramatically degenerated. The incorporation of LDHs could inhibit the oxygenic groups increase in asphalt molecules during ageing, and retard the gelatinization of colloidal structures. LDHs could alleviate the negative effect of ageing on asphalt, and improve the anti-ageing performance of asphalt. The improvement effectiveness of LDHs on the anti-ageing performance of asphalt was remarkably improved after MPMS modification.

Abstract ：
Asphalt mixture is a typical granular material, and its macroscopic properties are closely related to the interaction behavior of aggregate particles at the micro scales. Discrete element method (DEM), as an important numerical simulation method in granular mechanics, plays an increasingly important role in analyzing the aggregate packing characteristics, skeleton features, predicting mechanical and pavement performance of asphalt mixtures. However, the complexity of the composition of asphalt mixtures, including the particle size, shape, spatial distribution of aggregate particles, and the viscoelasticity of asphalt binders sensitive to temperature, load, and time, increases the difficulty of constructing DEM models of asphalt mixtures, selecting contact constitutive models, and determining parameters, which directly affects the accuracy and efficiency of DEM simulations. In this review, the generation methods of idealized models, image models, and user-defined models currently used to generate DEM models of asphalt mixtures were summarized in detail. Conventional contact constitutive models, including elastic and viscoelastic contact stiffness constitutive models, as well as fracture models including bonding models and cohesive softening models, were discussed. Moreover, special contact constitutive models, such as damage, self-healing, and two-stage contact models considering compaction evolution, were also summarized and discussed. Then, the contact constitutive model parameters were classified and related determination methods were summarized, and the latest application directions of DEM in current asphalt mixture research were classified. On this basis, relevant discussions were carried out, and the challenges and future development prospects faced by DEM in asphalt mixture research were proposed.

Abstract ：
The use of soil tuff, an industrial solid waste, for the modification of lead-zinc tailings as subgrade fillers presents a sustainable solution for concurrently addressing the negative impacts of tailings accumulation and resource depletion resulting from road construction. To demonstrate this, we conducted a thorough series of macroscopic and microscopic experiments, including the physical performance, durability, and microstructural behaviors of soil tuff-modified lead-zinc tailings sand (STM-LZTS) and cement-modified LZTS with varying modifier dosages, compaction degrees, and curing ages. Furthermore, we conducted a comprehensive comparison of the sustainability performance of these two modified LZTSs in terms of cost, CO2 emissions, and energy consumption. The results indicate that the incorporated 6% soil tuff filled the voids with the hydrated calcium silicate gel generated during the hydration process, which improved the structural stability. The CBR value was further enhanced to over 4% upon modification. With an increase in compaction degree to 96%, the CBR value escalated to over 8% (>4%). The STM-LZTS specimens exhibited compressive strengths ranging from 0.818 to 0.958 (>0.3 MPa). The variations in shear strength ranged between 200 and 550 kPa. Meanwhile, the modification of LZTS with soil tuff considerably delayed the deterioration of specimens under dry-wet, freeze-thaw, and salt-solution immersion conditions. Furthermore, compared with the cement-modified LZTS, the modified material formed a denser binder and a more robust nonparticle gel due to its lower calcium-silica ratio and higher aluminum-silica ratio, exhibiting superior performances in terms of compressive strength and resistance to salt corrosion. In addition, the use of soil tuff substantially reduced the cost, carbon emissions, and energy consumption, making it a promising and ecofriendly alternative for waste management and achieving carbon neutrality goals in subgrade engineering.

Abstract ：
Purpose The macropore structure and seepage characteristics profoundly influence the stability of granite residual soil (GRS) slopes. However, accurately predicting the permeability of undisturbed GRS (U-GRS) is challenging owing to its complex and susceptible pore structure. Aims and methods Employing X-ray computed tomography (CT) technologies, a three-dimensional (3D) pore structure of U-GRS, was established. Permeability prediction for U-GRS samples was conducted using three simulation methods, namely, the pore network model (PNM), finite element method (FEM), and the lattice Boltzmann method (LBM), along with two empirical models (EMs)-specifically, Kozeny-Carman (K-C) and Katz-Thompson (K-T) models. Subsequently, the methods were comparatively analyzed for calculating efficiency and accuracy. Finally, a piecewise permeability prediction model (PPPM) for U-GRS based on the CT-LBM was proposed. Results The ranking of permeability estimation methods in terms of accuracy was as follows: LBM > PNM > FEM > EMs. Substantial disparity was observed in the permeabilities obtained using both FEM and EMs compared to other methods, which exhibited a deviation of up to six orders of magnitude. The PPPM demonstrated smaller prediction deviations than the EMs, with its accuracy influenced by the strategy for selecting calculation parameters. Conclusion The CT-LBM, which uses real pore structures, was employed to estimate the permeability of U-GRS. The PPPM, established based on this method, was found to be applicable for estimating U-GRS permeability.
