| 摘 要： | 在水平匀速滑坡涌浪传播过程中,当滑坡体匀速前进时,会形成一个冲击波,停止前进后,在滑坡体与冲击波之间又形成一个稀疏波,当稀疏波追赶上冲击波时,两个波则会发生相互作用。对稀疏波与冲击波相互作用后产生的反射冲击波和入射冲击波的情况进行了定量研究。从入射冲击波的轨迹方程入手,通过分析和计算,分别得到了入射冲击波和反射冲击波波高、波速等一些定量的关系式,并用简单的计算方法进行了求解。

| Abstract: | During the propagating processes of the level and uniform velocity landslide bore,a shock wave is formed when the landslide object is advancing at the uniform velocity.When it stops advancing,a rarefaction is formed between the landslide object and the shock wave Then the interaction will occur when the raretact ion cat ches up with the shock wave.The article provides a quantitative research on the reflection shock wave and the incidence shock wave generatd by the interaction.Based on the track equations of the incidence shock wave,some quantitative relations between wave heights,wave speeds and others concerned are obtained,and some simple computing methods are presented to solve them. |
