摘　　要：选择某水电站近坝段的一个典型滑坡体作为研究对象,对天然河道建立数学模型进行涌浪传播过程的数值模拟,得到了涌浪沿河道传播衰减规律和涌浪淹没范围。结果表明涌浪传至坝址处一定高度时,不会对坝体安全产生破坏性影响,为库区移民和防灾减灾提供了参考依据。The mathematic model of natural river course was built by consider a typical landslide near the dam area of one hydropower station. Then, the numerical analysis of surge propagate was conducted to get the reduction law of surge propagate along the river course as well as the surge submerged area. The result shows that surge won＇ t produce a destructive influence to the safety of dam when the surge reduced to a certain height at dam site, which provides a reference for Reservoir resettlement and Disaster prevention and mitigation.
