Summary: This study presents stability analyses of layered soil slopes in unsaturated conditions and determines the factor of safety involving suction stress of unsaturated soil using a limit equilibrium method. The obtained results show that larger suction stress provided in unsaturated clay dominates the stability of the layered slopes, while the location and thickness of the clay layer have significant influences on slope stability.

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 proposes a method for evaluating the risks of slope failure induced by heavy rain. The method combines infiltration analysis, surface flow analysis, and slope stability analysis using a three-dimensional limit equilibrium method. It is found that this method can roughly represent actual slope failure and the use of high-resolution terrain data obtained from UAVs is important in evaluating micro-topography stability.

Summary: A new three-dimensional slope stability analysis method is proposed based on the finite element method for stress calculation. The method can easily calculate both local and global safety factors of the slip surface and uses an improved ellipsoidal slip surface construction method and two-stage particle swarm optimization to search for the critical slip surface more accurately. The study reveals the influence of various factors on the calculation results and validates the effectiveness of the proposed method through numerical examples and comparison with the strength reduction method.

Summary: The failures of volcanic crater-rims can lead to the avalanches of glowing rocks, which pose a serious threat to inhabited areas. This study analyzed the slope stability of the crater-rim of Stromboli volcano in Italy and found that the collapses were frequently associated with high-level of magma. The researchers considered various factors, such as the nonlinear failure envelopes of volcaniclastic material and seismic ground acceleration, in their analysis.

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: This study proposes a more practical calculation method for slope degradation, and its effectiveness is verified through engineering examples. The results show that the strength of slope rock mass is significantly reduced after blast disturbances, and the calculated CSF is closer to the results of the limit equilibrium method. The NSCR method addresses the drawbacks of the traditional method in double-parameter reduction and is practical and feasible for slope stability analysis.

Summary: In this study, the tsunamigenic event at Stromboli volcano in Italy on 30 December 2002, induced by volcanic landslides, is re-examined using visible images and slope stability analysis. The study presents the results of stability analyses and a sequence of photos collected before the collapse. The findings suggest that the landslides triggering the 2002 Stromboli tsunami were the result of a lateral magma intrusion destabilizing the slope.

Summary: Transportation infrastructure in mountainous terrain and river valleys are susceptible to various landslide phenomena. Remote sensing techniques offer a way to enhance monitoring tools for geotechnical engineers, improving identification of landslides, complementing in-place instrumentation, and defining landslide extents and deformation mechanisms. The application of these techniques in Western Canada has provided practical insights for risk management strategies in dealing with landslide hazards.

Summary: Historically, tailings facilities were designed with limited consideration for their long-term management. In Alberta, Canada, dam owners can apply to de-register the facility as a dam and reclassify it as a regulated mine waste dump. To support this process, a risk management tool called the G-FMEA framework was developed and applied to an oil sands tailings dam in Alberta. The framework assessed two specific failure modes and demonstrated how the risk rating may change over time.

Summary: Research indicates that the Ripley landslide in the Thompson River valley has been moving at a very slow to slow rate, with a near-horizontal movement closer to the toe of the landslide and an increased vertical deformation near the scarp. This suggests that the Ripley landslide is a compound landslide, similar to older landslides in the area.

Summary: Understanding the kinematics and factors contributing to landslides is crucial for infrastructure decision-making. The Interior Plains region in Canada shares some common geomorphological features, including thin sub-horizontal weak formations and seasonal fluctuations in water bodies. Human activity can also trigger landslides in this region.
