山区河道型水库滑坡涌浪爬高试验研究

Experimental research on landslide surge run-up of the river-channel type reservoir in mountainous area

以三峡库区大型滑坡为研究对象,通过水槽概化模型试验,得到滑坡涌浪爬高随滑坡体宽度与厚度、滑动面倾角、水深等因素的变化规律;采用多元回归分析,得出爬高与初始浪高、水深、爬高测量点与滑坡体的入水点距离、岸坡坡度的经验计算公式,计算值与实测值较吻合。研究成果可为滑坡涌浪灾害的预测预警提供科学依据。

Select the large-scale landslide in the Three Gorges Reservoir Area as research object,this paper got the law of landslide surge run-up with variations of the width and thickness of the landslide,the sliding surface angle,or depth.And it has obtained the run-up empirical formula by the multiple linear regression method among the primary wave height,the depth,the distance from point that landslide go into the water to run-up measurement point and the slope angle.The calculated and measured values agree well.The research result can provide scientific basis for landslide damage prediction and pre-warning.
