土钉路堑边坡的稳定性分析方法

The analysis method of stability of cutting slope of soil nail

土钉边坡方案设计完成后 ,如何采用合理的方法进行其稳定性分析 ,一直是人们所关心的问题 .笔者在极限平衡分析理论的基础上 ,采用Sarma法提出的扰动力的概念建立土钉墙支护条分法数学模型 ,采用单纯形优化方法确定最危险滑动面 ,从而建立土钉路堑边坡的稳定性分析方法 .

After finishing designing a side slope plan of soil nail,a problem which people have always paid attention to is how designers adopt reasonable method to analysize side slopes stability of soil nail.Based on limit equilibrium analysis theory,this paper puts forward the stability analysis method of cutting side slope of soil nail by using the concept of disturbance power put forward by Sarma to build mathematical model of soil nail wall supportings slices method and using simplex optimization method to confirm the dangerest slide face.
