摘　　要：泥石流是一种典型的公路水毁病害,也是公路水毁时主要破坏动荷载,遵循泥石流的运动规律和道路破坏特点,建立泥石流防治技术是治理公路水毁病害的关键。文章通过分析泥石流体的运动特点,提出了合理的速流槽泥石流防治结构剖面形状,根据能量守恒原理建立的泥石流体运动方程和根据平抛理论建立的泥石流体抛程计算公式,解决了泥石流防治结构受泥石流体作用力大小的计算和泥石流防治与公路水毁病害治理效果的理论判断问题,为同类型的特大型公路泥石流防治结构设计与公路水毁病害治理提供了理论依据。Debris flow is a kind of typical water ruins to highways, and it is a dynamic load for highway water ruin. The authors, following the moving law of debris flow and characteristics of highway ruin, put forward reasonable section shape of high - speed drainage trough. Then, according to the energy conservation principle and horizontal throwing theory, the authors established a calculation formula for the throwing distance. The results of the calculation formula given in this paper offer a solution for load calculation and control effect evaluation problems and provide theoretical foundation i to structure design and disease control of debris flow along the highways.
