摘要
基于波状泥石流运动的基本方程，即浅水波方程，本文中分析了运动速度与形状保持不变的波状泥石流波面形态，并与蒋家沟实测４阵波状泥石流波形在运动过程中变化的波状泥石流，作者在明槽中进行了模拟试验，并用特征线方法做了相应计算，试验测量结果包括固定点泥位变化，不同时间泥石流波峰位置及波状泥石流最终停积形态；计算结果包括波状泥石流的运动过程，从开始运动、中间任一时刻波状泥石流的位置及波形。
Based on the fundamental equations of debris flow sunes(or shallow water waves),thesurface wave profiles of debris flow are analyzed with the assumption that both the velocity andthe surface profile keep unchanged during the motion of debris flow.The verifieation is made incomparison with several gusts of surface profiles measured in Jiangjia Gully as well as some simulated profiles of flow surface and velocity from laboratory. The latters are well fitted with thecalculated results from the characterstic line method.Measurements are made on depth variation.wave crest propagation and the final sedimentary pattern of debris flow. All of which arereasonably described by the theory.
