中文摘要：

采用传统的极限平衡法，利用边坡稳定分析不同方法对高填路堤三种边坡形态影响因素：填土高度、路堤边坡坡比、地基倾斜角取不同的值进行了安全系数的计算并做了对比分析。在此基础上，采用灰色关联分析方法对边坡稳定进行敏感性因素分析。经分析，路堤的倾斜角对边坡稳定性影响最为敏感，而路堤填筑高度次之。利用有限元分析中的强度折减法对不同地基倾斜角分别在三种失稳判据下进行了安全系数计算，并与极限平衡法进行对比，结果显示安全系数相差不大。经过后处理功能得到边坡位移等值线云图，确定了滑动面的形状为圆弧状及其位置。

英文摘要：

Based on the limit equilibrium method ,the different methods were used to carry out the calculation and analy -sis of safety factor in three different influencing factors about the slope shape of high embankment ,including the depth of embankment ,ratio of slope and bank angle .Based on this ,the grey correlation analysis method was used to carry out the sensibility analysis of slope stability .Through calculation ,the result suggests that the bank angle is the most sensitive factor and the embankment depth is second .Simultaneously ,the strength reduction FEM is used to calculate the safety factor of the slope in three different unstablity conditions when the slope angle is different ,and its result is in accord with the solution from the limit equilibrium method which is known by comparison .After processing ,the displacement nepho-graph of slopes is got ,and the arc shape and location of slip surface are confirmed .
