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 ：
The aim of this research is to explore the feasibility of using tailings sand (TS) as a partial replacement for sand in the production of cement-stabilized base course materials. In this paper, the performance, economic and environmental benefits of cement-stabilized tailings sand-gravel base material (CSTSM) with various TS content were comprehensively studied. The results indicate that the mechanical properties, drying shrinkage strain and durability of CSTSM decreased with the increasing TS content (0%-30%) while adhering to the necessary engineering requirements (UCS>2.4 MPa). The TS inclusion reduces hydration product coverage, decreases compactness and increases porosity, resulting in reduced strength and durability of CSTSM. When the TS content is below 16%, the deterioration in mechanical properties and durability of CSTSM under dry-wet, freeze-thaw and sulfate corrosion conditions is relatively minor, sufficiently meeting with the heavy traffic demands on highway subgrades (UCS>4 MPa). Moreover, when compared to ordinary cement-stabilized base course materials, the use of TS reduces the cost and CO2 emissions. After a comprehensive comparison of performance, economic benefits and environmental factors, a 16% TS substitution ratio is recommended for achieving optimal outcomes. Utilizing CSTSM in subgrade engineering is promising and environment-friendly approach for large-scale solid waste treatment and achieving carbon neutrality goals.

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 ：
The embankment of an S-shaped gully (E-SSG) has a specific topography, which results in its unique shape effect. However, how the shape effect of the E-SSG is generated, how it relates to different geometric variables, and how it can be considered in slope stability analysis remain unknown. Hence, this study examined this shape effect using the finite-element strength reduction method to analyze the spatial stress and displacement distribution. In addition, the gray correlation method was introduced to determine the link between the shape effect and the terrain factors. Furthermore, the shape effect within the steep slope of an E-SSG was considered and a dimension-reduced (DR) slope stability analysis technique was proposed. Upon obtaining the link between the shape effect and the terrain factors, the shape effect factor psi can be calculated. A psi value >0.062 indicated a shape effect on the E-SSG. On this basis, the three-dimensional safety coefficient of the E-SSG can be obtained using the spatial-effect trends and the safety factor via the DR approach (i.e., the two-dimensional model). Finally, the rationality and accuracy of the proposed method were validated using engineering cases. Moreover, generation mechanisms and principal determinants of the shape effects within the steep-slope embankments under S-shaped and V-shaped gullies were compared. It was learned that the E-SSG is an asymmetric structure compared with the V-shaped gullies, and the stable right base bank is an important factor in the shape effect of the E-SSG.

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 ：
Foamed lightweight soil (FLS) is frequently used for roadbed backfilling; however, excessive cement use contributes to higher costs and energy consumption. Desulfurized gypsum (DG), a by-product of industrial processing with a chemical composition similar to natural gypsum, presents a viable alternative to cement. This study evaluates the potential of DG to replace cement in FLS, creating a new material, desulfurized gypsum foamed lightweight soil (DG-FLS). This article is conducted on DG-FLS with varying DG content (0-30%) to assess its flowability, water absorption, unconfined compressive strength (UCS), durability, and morphological characteristics, with a focus on its suitability for roadbed backfilling, though its performance over the long term in engineering applications was not evaluated. Results show that as DG content increased, flowability, water absorption, and UCS decreased, with values falling within the range of 175-183 mm, 8.24-12.49%, and 0.75-2.75 MPa, respectively, all of which meet embankment requirements. The inclusion of DG enhanced the material's plasticity, improving failure modes and broadening its applicability. Durability tests under wet-dry and freeze-thaw cycles showed comparable performance to traditional FLS, with UCS exceeding 0.3 MPa. Additionally, the incorporation of SO42- in DG-FLS reduced sulfate diffusion, decreased C-S-H content, and increased calcium sulfate content, improving sulfate resistance. After 120 days of exposure to sulfates, the durability coefficient of DG-FLS surpassed 100%, with a 25% improvement over traditional FLS. A sustainability analysis revealed that DG-FLS not only meets engineering strength requirements but also offers economic and environmental benefits. Notably, DG-12 showed a 20% reduction in environmental impact compared to conventional FLS, underscoring its potential for more sustainable construction.

Abstract ：
In order to characterize the mesoscopic seepage of pore spaces within undisturbed granite residual soil (UGRS). The 2D/ 3D pore models of UGRS were reconstructed using computed tomography (CT) scanning and image processing technology. The lattice Boltzmann method (LBM) was employed to simulate the seepage displacement process and water distribution in UGRS pores through programming. Results indicate that isolated pores have minimal impact on seepage outcomes. Only a few large, straight pores with good connectivity become dominant channels, generating preferential flow. Throughout the seepage process, the maximum velocity in the dominant passage shifts from the inlet to the middle and then to the outlet region. The influence of pore structure characteristics on seepage is more significant than pore proportion. Using industrial CT scanning technology and LBM provides a better description of real soil pore flow. The 2D model intuitively illustrates the preferential flow phenomenon of macropores, suitable for qualitative research. The 3D model, closer to reality, accurately calculates soil permeability, making it suitable for quantitative research. © 2024 Editorial Board of Journal of Basic Science and. All rights reserved.
