摘　　要：泥石流具有强烈的冲击破坏作用,是防治结构和穿越泥石流沟谷其他建筑物毁损的重要影响因素,笔者在文中基于流固耦合的基本理论,运用有限元程序ADINA对西昌平川泥石流中的速流结构在泥石流冲击作用下的动力响应进行数值模拟,通过对水平位移和应力的分析,得到了一些有益的结论.Debris flow has strong impact and destroying energy, and is the mostly factor which damage the controlling construction and others through the debris flow valley. Based on the primary theory of fluid-structure coupling problem, the paper attains dynamic responses of High-speed Drain Structure under debris flow impact by using the ADINA procedure, and also gains some useful conclusions by way of analyzing the plane displacement and stress.
