The initial impoundment of the Baihetan reservoir region (China) exacerbated the deformation of the Wangjiashan landslide: characteristics and mechanism

Xiaoyu Yi et al.

Summary: Reservoir landslides pose a significant threat to reservoir safety. Understanding the deformation characteristics and mechanisms of these landslides is crucial for assessing their stability and preventing secondary disasters. In this study, the authors analyzed the deformation characteristics and reactivation mechanism of the Wangjiashan ancient landslide during the initial impoundment of the Baihetan Reservoir region. They found that the landslide slowly deformed before impoundment, but impoundment itself drove further deformation. The rise in reservoir water level resulted in bank collapse at the landslide toe, followed by creep deformation and overall sliding. Moreover, the study revealed that the WJS landslide is a buoyancy weight-reducing landslide, where the reservoir water buoyancy acts on the resisting section and reduces its resisting force, leading to rapid sliding.

Modelling the evolution of propagation and runout from a gravel-silty clay landslide to a debris flow in Shaziba, southwestern Hubei Province, China

Xudong Hu et al.

Summary: This study utilized numerical modelling to analyze the kinematic characteristics of a landslide-generated debris flow event in Shaziba, Enshi City, that occurred on June 8, 2020. The results showed overall acceleration in the initial stage, and the movement of gravel-silty clay materials lasted for a considerable amount of time, providing valuable insights for understanding the dynamics of similar geological hazards.

Investigation and characteristic analysis of a high-position rockslide avalanche in Fangshan District, Beijing, China

Wenpei Wang et al.

Summary: In August 2018, a high-position rockslide avalanche occurred in Da'anshan village, Fangshan district, Beijing, China, causing no casualties due to timely warning detection. The displaced material traveled a horizontal distance of about 260 m with a vertical drop of about 176 m and finally accumulated with a volume of about 24,000 m(3). This study provides a methodological reference for future simulation analysis of similar events.

Deformation characteristics, mechanisms, and influencing factors of hydrodynamic pressure landslides in the Three Gorges Reservoir: a case study and model test study

Shimei Wang et al.

Summary: Hydrodynamic Pressure landslides in the Three Gorges Reservoir are the most typical landslides affected by water level fluctuations, exhibiting large overall deformation characteristics. The deformation is mainly influenced by the overall deformation of the landslide front edge, with the back part experiencing tensile deformation. The deformation trend is increasing due to the periodic changes in reservoir water levels.

Mechanical energy evolution in the propagation of rock avalanches using field survey and numerical simulation

Yunfeng Ge et al.

Summary: By studying the propagation process and energy evolution of rock avalanches, it was found that more collisions occurred in the front portion of the sliding mass, resulting in blocks in this area receiving more energy and traveling a longer distance.
