摘　　要：为研究滑坡涌浪的形成与传播规律,采用正交试验方法设计试验组次,针对整体滑坡体与散体滑坡体进行了滑坡涌浪物理模型试验研究;通过极差分析与方差分析得到了首浪高度随各因素的变化规律;通过量纲分析与回归分析给出了整体滑坡体的首浪高度经验公式,并与散体滑坡体首浪高度经验公式进行了比较。研究成果可为滑坡体的致灾预测预警提供科学依据。For studying the forming and propagation laws of surge generated by a large landslide, by adopting orthogonal experimental method to design experiment groups, we carried out the physical model experiment study aiming at solid-type landslide and loose - type landslide body. The variation law of primary wave height with different factors was obtained from extreme differ- ence and variance analysis. The empirical formula of primary wave height caused by solid - type landslide was deduced by dimen- sional and regression analysis respectively. And differences of both were compared. The research result can provide scientific ba- sis for landslide~ damage prediction and pre - warning.
