Difference Analysis of Wave Disaster Characteristics Induced by Landslides of Different Water Entry Scales
Published 2024-01-01“…This paper conducts a three-dimensional numerical analysis on the surges generated by landslides of different water entry scales,and analyzes the characteristics of surge disasters induced by landslides of different water entry scales, such as surge height, surge speed,and bank climbing height.Meanwhile,the impact of surges caused by landslides of different water entry scales on the dam is explored.The FLOW-3D numerical simulation method is employed to simulate and analyze the entire process of landslide instability,surge formation and propagation,surge climbing,and surge backflow.The results show that the maximum climbing height of the surge generated by the 3.1 million m<sup>3</sup> landslide of water entry is 54.5 m on the opposite bank,and the surge height in front of the dam is 6.69 m.The surge has a small area of overflow at the right bank dam shoulder.The surge generated by the 0.8 million m<sup>3</sup> landslide of water entry has a maximum climbing height of 26.00 m on the opposite bank,and the surge height in front of the dam is 5.38 m,without influence exerted by the surge on the dam safety.The results indicate that the induced surge caused by 3.1×10<sup>6</sup> m<sup>3</sup> landslide of water entry is more catastrophic than that brought by 0.8×10<sup>6</sup> m<sup>3</sup> landslide of water entry.…”

Formation Mechanism and Stability Analysis of the Hejia Landslide
Published 2021-01-01“…Through field investigation and analysis of regional geological conditions, it is concluded that Hejia landslide is a large-scale landslide, through long-term sliding-bending deformation; it is generated from the external hard rock with thick layers and sliding zone for layered soft rock; the formation mechanism of landslide is as follows: (1) high-steep and hard-soft layered slope is the slope structure condition that caused the large landslide; (2) the existence of thick soft rock belt provides material conditions for the formation of slip surface; (3) certain air conditions provide displacement space for the separation and disintegration of the sliding body, and the landslide is stable at present. Numerical analysis results show that reservoir impoundment will adversely affect the stability of landslide. …”
