摘　　要：针对稀性泥石流特点 ,从垂直于排导槽边壁方向和平行于排导槽边壁方向对排导槽的受力情况进行了比较深入的分析 ,导出了多个公式 。This paper first makes an introduction to turbulent debris flow(subviscowse debris flow)destroying drainage canal,then simply summarizes the characteristics of the turbulent debris folw;thirdly deeply analyses drainage canal from two directions:one is vertical to drainage canal wall,the other is equal to drainage canal wall.In addition this paper also obtains ten formulae (seeing the paper).For this reason,this paper provides designing basis for drainage canal.

关 键 词：稀性泥石流 排导槽 破坏机理 边臂方向 磨损
