摘要：
Slopesaround the reservoir area may be damaged by strong earthquake or rainstorm and slide into the reservoir which can induce huge surge hitting on dams. In this paper, the surge generation and propagation process and the distribution pattern of impacts on dam's surface induced by landslide surge were studied using the smoothed particle hydrodynamics (SPH) method. The influences of particle space, initial falling velocity, water depth and slider width etc. on the surge wave height and impact pressure on dam surface were analyzed. The results show that the maximum wave height decreases with the increase of the width of the landslide mass, whereas the following wave amplitudes increase and intensity of impact pressure on dam surface increase; the amplitude of surge wave increases with the increase of initial falling velocity of landslide mass, whereas when it increases to exceed a certain extent, the intensity of impact pressure does not change obviously; the amplitude of the first surge wave height decreases with the increase of water depth of the reservoir, where the maximum impact pressure and its relative position to water surface are basically unchanged © 2018, China Water Power Press.
