In this study, the experimental investigation on whether the landslide surge waves can influence the dam failure process caused by flood overtopping was presented. The experiments were conducted in a large width flume with length of 50 m, width of 4 m and height of 2 m. The time between the start of the earth dam break and the surge wave reaching the dam site was set to 80 s. During this period, the water depth of the reservoir constantly decreased. The experimental results showed that the surge wave height decreased while the propagation velocity increased slightly as the surge moved to the dam site. Several surge waves could overtop the dam crest and the shear height of the dam crest caused by each surge wave was a function of the surge wave height, which could be described non-dimensionally by Δz* = 0.946 H_s*^2.113. The surge wave influenced the water level falling velocity and breach width expanding speed from the time of the overlay of the breaking dam. The surge wave could lead to a large instantaneous peak discharge that exceeded the dam failure peak discharge of the experiments with no surge wave.

在这项研究中，提出了关于滑坡浪涌波是否可以影响由洪水超顶引起的大坝破坏过程的实验研究。实验是在长50 m，宽4 m，高2 m的大宽度水槽中进行的。从土坝破裂开始到浪涌到达坝址的时间设置为80 s。在此期间，水库的水深不断减小。实验结果表明，随着涌浪移向坝址，涌浪高度降低，传播速度略有增加。几个浪涌可能会超出坝顶，并且每个浪涌引起的坝顶剪切高度是浪涌高度的函数，可以用无量纲描述Δz * = 0.946^ h_小号* ^2.113。从破坝的覆盖时间开始，浪涌波影响了水位下降速度和裂口宽度扩展速度。浪涌可能导致较大的瞬时峰值放电，超过没有浪涌实验的大坝破坏峰值放电。
