Summary: This study investigates a landslide in northeastern Taiwan caused by high groundwater levels due to continuous rainfall. Through finite element limit analysis and Hoek-Brown failure criterion, reasonable key parameter ranges were deduced for slope stability. The results indicate the importance of geological strength index (GSI) and disturbance factor (D) for the stability of closely jointed and weathered bedrock slopes in the region.

Summary: Flexural toppling is a failure mode of anti-dip rocks that occurs during earthquakes, with high speed and extreme energy resulting in catastrophic consequences and huge losses. However, there is limited literature on its failure mechanisms and the failure surface caused by earthquakes. This study applied the horizontal pseudo-static load to improve the geological mechanical model and analyzed the failure surface and mode of the slope under different seismic loads. The results showed that increasing seismic load led to an increase in the number of rock layers with cantilever toppling failure and a decrease in the number of rock layers with overlapping toppling failure, causing decreased stability of the anti-dip rock slope under earthquake conditions.

Summary: The research focused on the stability of rock slopes and the influence of spatial variability on slope stability, showing that the spatial variability of weak layers has a greater impact on slope stability under seismic loading than that of rock material. The influence of seismic randomness cannot be neglected in slope failure analysis.

Summary: A new creep model was developed to simulate time-dependent responses of jointed rock mass, and its implementation in UDEC demonstrated the influence of joint properties on the long-term stability of rock masses. A case study of a high rock slope in western Norway analyzed the creep deformation mechanisms of the rock mass and found no unstable movement on potential sliding surfaces. The proposed creep model provides a novel approach to analyze structural failures of jointed rock mass under creep loading conditions.

Summary: An exact solution for stability measures was derived, which satisfies both equilibrium and compatibility, and was applied to evaluate the stability factor and factor of safety for infinite rock slopes governed by the Hoek-Brown criterion, considering the presence of parallel seepage flow. The generalized Hoek-Brown criterion was directly utilized without typical approximations.

Summary: Despite its potential, GIS-based kinematic stability analysis in rock slopes is rarely used in geological engineering. This article presents a modified technique that utilizes GIS software to assess kinematic analysis in predicting shallow landslides in the Himalayan mountains. The technique's limited use is due to practical complexities, which are addressed through modified methods and a new application called 'GISMR'. The study demonstrates the strong relationship between kinematic susceptibility and landslide activity in the region.

Summary: The stability of rock slopes with weak planes was evaluated using empirical slope mass rating (SMR) and kinematic analysis, and a mechanical-based method was used to study the effects of weak plane orientations. The results showed that the SMR values and numerical safety factors exhibited similar trends, indicating the rationality of the approach. The determination of the lateral limit angle in kinematic analysis was found to be subjective, requiring consideration of actual conditions for accurate assessment.

Summary: This study improves the original program of the finite-discrete element method (FDEM) to simulate the dynamic instability process of earthquake-induced landslides. The improved FDEM accurately reproduces the dynamic evolution processes and failure forms of different jointed rock slopes under seismic load, and quantitatively evaluates their dynamic stability. The study also emphasizes the influence of the slope failure degree on the dynamic response and proposes criteria for slope dynamic instability simulation using FDEM. This research provides scientific and technological support for understanding the failure mechanism of jointed rock slopes and disaster reduction.

Summary: The stability of toe-cut slopes is significantly affected by external factors, with rainfall having a smaller impact compared to excavation height. Reinforcing toe-cut slopes with pile-anchor structures can effectively improve stability under rainfall and earthquake conditions. This study provides important guidance for the prevention of geological disasters in mountainous areas.

Summary: This study investigates the mechanism and influencing factors of displacement mutation in jointed rock slopes caused by blasting excavation through field monitoring and numerical simulations. The results show that the displacement mutation is closely related to the combined actions of blast loading and transient in-situ stress release. The rapid release of rock strain energy leads to joint opening and displacement mutations in jointed rock slopes.

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: Rock slope stability analysis can be performed using deterministic and probabilistic approaches, with the latter offering a more rational way to quantify risk by considering input variable uncertainty. Various methods such as Monte Carlo simulation, point estimate method, and response surface method are used to evaluate the probability of failure in rock slope stability analysis. Although these methods may be complex, they provide a more comprehensive definition of risk in slope stability analysis.
