| 摘 要： | 泥石流是我国常见的一种地质灾害.位于泥石流区的公路路基常常由于受到泥石流的冲击而毁损严重,甚至导致交通的中断.泥石流冲击路基是一个复杂的三维问题,通过分层法将其简化为平面问题,建立了泥石流冲击作用下路基毁损的力学模型,并通过稳定性分析和叠加原理得到了确定冲击坑形状的计算方法.最后通过将泥石流冲击坑的形状与路基自稳的临界...

| Abstract: | Debris flow is one of the familiar geological disaster in China.The debris flow not only destroyed the roadbed but also intermitted the traffic.Actually,debris flow impacting the roadbed is a complicated three dimension problem.In order to solve this problem,the three dimension problem is simplified to plane problem by a layered approach.Based on the simplification the physics model is established for debris flow impacting the roadbed.And through the stability analysis the calculate method for the form of i... |
