摘要
Abstract
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 m3 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 m3 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 3.1×106 m3 landslide of water entry is more catastrophic than that brought by 0.8×106 m3 landslide of water entry.关键词
