Summary: A new limit equilibrium method is proposed for evaluating the stability of cable-reinforced high bedding rock slopes subjected to rotational bi-planar failure. The proposed method is validated through tilt-test physical modeling and discrete numerical simulations, and its results are found to be in good agreement with those obtained from traditional slice methods. The location of the prestressed anchor cable has a significant impact on the safety factor of the slope, while the anchorage angle has almost no effect.

Summary: This paper investigates the reliability analysis of slopes under a nonlinear failure criterion by generating two-dimensional random fields using Karhunen-Loeve (KL) expansion method. The simplified Bishop's method with a nonlinear failure criterion is used to calculate factor of safety based on the generated random fields. Monte Carlo simulation is then utilized to estimate the slope's reliability. Example analyses are conducted to validate the proposed method. The effect of the nonlinearity coefficient m on the failure probability of slopes is also examined, showing that the failure probability obtained using the nonlinear failure criterion is higher than that calculated using the linear Mohr-Coulomb criterion.

Summary: This study analyzes the seismic internal stability of the bilinear geosynthetic-reinforced slope (BGRS) to determine reinforcement forces, finding that ignoring cohesion of backfill and/or vertical seismic loads can benefit conservative stability analysis. The existence of tension cracks affects the distribution of reinforcement forces in the upper and lower tiers. Additionally, changes in critical slip surface volume are observed under global stability conditions with varying angles of the lower tier, cohesion of backfill, depth of tension crack, and seismic coefficients.

Summary: Dynamic centrifuge model tests were conducted to study the seismic performance of sand slopes under different earthquake ground motions and slope angles. The results showed that increasing earthquake intensity led to a decrease in soil rigidity, an increase in damping ratio, and an increase in both dynamic response and predominant period of slopes; different ground motions caused the acceleration response spectra of slopes to be completely different, with the Northridge seismic wave with low-frequency component being closest to the predominant period of the slope model; the slope angle was found to affect the acceleration response and predominant period of slopes.

Summary: This paper investigates the effect of seismic force on the stability of locally loaded slopes and proposes an accurate mechanical approach based on the limit analysis method. By using a 3D rotational velocity field, the limit load on the slope top is obtained, which improves the existing upper-bound solutions obtained by using the translational velocity field. Parametric analysis shows that the limit load increases with the increase of a/H or the internal friction angle phi, but decreases as the slope angle beta or the length-to-width ratio (L/t) of the local load increases. Additionally, the limit load decreases with the increase of the seismic coefficient k h and is proportional to the seismic coefficient.

Summary: This study focuses on the stability and biplanar failure of concealed cataclinal slopes with talus deposits accumulated at their toes (TDAT-CC slopes), proposing a new method to determine slope stability and predict failure surface. It was found that talus deposits at the toe of the slope act as a toe buttress improving slope stability, with the safety factor increasing as the inclination and height of the deposits increase. The results obtained offer a solid foundation for investigating biplanar failure in TDAT-CC slopes.

Summary: This paper investigates the estimation of fracture size- and azimuth-related parameters in the universal elliptical disc (UED) model based on trace information from sampling windows. The stereological relationship between trace length and UED parameters is established, and formulae for mean value and standard deviation of trace length are proposed. Monte Carlo simulations validate the proposed formulae with less than 5% error rate. An optimization method is developed for parameter estimation using trace length. A case study demonstrates the effectiveness of the method, and a three-dimensional hypothetical fracture network shows the superiority of the UED model over circular disc and non-UED models.

Summary: In this paper, an improved Newmark displacement model that considers the accumulation of dynamic pore water pressure (DPWP) in the soil caused by both vertical and horizontal ground motions is proposed. The seismic slope displacement analyses indicate that the weakening effect of slope yield acceleration caused by bidirectional earthquake excitation-induced DPWP is more obvious than when only considering the horizontal ground motion when the slip surface soils are in near-saturated state. The numerical results show that the seismic displacement model seldomly considering the effect of DPWP, or only considering the DPWP induced by horizontal ground motion, can significantly underestimate the displacement value when the slip surface soils are in a near-saturated state.

Summary: Reliability-based design (RBD) of geotechnical works has achieved success but its application in real-world engineering practice is limited due to engineers' unfamiliarity with reliability algorithms and the lack of direct connection between reliability algorithms and deterministic design tools. This study proposes an inverse first-order reliability method (FORM) integrating adaptive conjugate direction search technique to solve classical RBD problems. The proposed algorithm performs robustly and efficiently, and has been successfully applied in risk-based optimization of unknown design parameters for soil slope stability models.

Summary: Although rainfall and earthquake are recognized as the most important factors for landslide, the failure mechanisms of a soil slope under these factors are different. This study uses numerical investigation to analyze the combined effect of earthquake and rainfall on slope instability. The results show that the strain-softening behavior of the soil significantly affects seismic slope displacement and post-earthquake rainfall can further deteriorate the shear strength, leading to landslides over time.

Summary: Creep and stress relaxation behaviors in granular materials are influenced by the time-dependent changes in their microstructure, with particle shape playing a significant role. However, the effects of particle shape on these behaviors are still not well understood. In this study, 3D DEM models incorporating the rate process theory and superellipsoids are used to simulate creep and stress relaxation in granular samples with different aspect ratios and blockiness. The results show that both aspect ratio and blockiness have a significant influence on creep and stress relaxation, with aspect ratio affecting creep through contact force ratio and blockiness affecting stress relaxation through variation in normal contact force anisotropy. These findings provide insights into the effects of particle shape on creep and stress relaxation in granular assemblies.

Summary: This paper presents a novel elastic-viscoplastic constitutive model that takes into account particle breakage to reproduce the time-dependent behavior of coarse-grained soil. The model integrates the Unified Hardening (UH) model, the elastic-viscoplastic (EVP) model, and the overstress theory. The relationship between particle breakage and loading rate is established, and state variables associated with the critical state of coarse-grained soil are derived to consider both time and particle breakage. A three-dimensional elastic-viscoplastic constitutive model is constructed by combining a one-dimensional viscoplastic hardening parameter with a secondary consolidation coefficient considering particle breakage. The proposed model requires 19 parameters and effectively describes the influence of time-dependency and particle breakage on the shear, dilatancy, and compression behaviors of coarse-grained soil with different confining pressures or initial void ratios. Experimental data comparisons validate the model's ability to replicate the time-dependent behavior of coarse-grained soil.
