摘　　要：为研究滑坡涌浪的形成与传播规律,采用正交试验设计方法设计了试验组次,进行了不同滑坡体体积、落差、受纳水体水深、滑动面倾角、散体粒径等因素条件下的滑坡涌浪物理模型试验研究。通过极差与方差分析,得到了首浪高度随各因素的变化规律;通过量纲与回归分析,给出了散体滑坡体的首浪高度经验公式。研究成果可为滑坡体的致灾预测预警提供科学依据。For investigating the forming and propagation laws of surge induced by landslide,by adopting orthogonal experimental method to design experiment groups,we carried out physical model experiment study under different influencing conditions concerning landslide volume,falling height,receiving water depth,slide plane dip-angle and granular diameter etc.The variation law of primary wave height relating to different factors is obtained from extreme difference and variance analysis.The empirical formula of primary wave height caused by loose earth landslide is deduced by dimensional and regression analysis.The research result can provide scientific basis for landslide＇s damage prediction and pre-warning.
