摘　　要：通过模型试验的方法,对滑坡涌浪在渐溃水库中的传播过程进行重演。研究表明,溃坝过程导致的库区水深下降对涌浪的波高、波长和周期均有很大影响;溃坝和非溃坝条件下,涌浪高度随时间衰减趋势都是相似的;相比非溃坝情况,渐溃条件下涌浪传播到坝体时波高衰减幅度更少。Two model experiments were conducted to performance the landslide surge propagation in a gradual dam failure reservoir.The research showed that the decrease water depth caused by dam-break would influence the surge wave height,surge wave length and surge period.The surge wave attenuation trend was similar with each other under the condition of dam failure and unfailure.Compared with the case of non-dam break,the surge wave height decrease less than dam break case when the surge reach the dam site.
