| 摘 要： | 基于边坡稳定性计算的简化Bishop算法，将阶梯形边坡简化成低阶或单阶边坡，并对简化前后的边坡稳定进行了计算，结果表明，简化前后得出的边坡安全系数十分接近，所确定的最危险滑动面位置基本不变，说明对阶梯形边坡进行简化计算是可行的，该结论对复杂边坡支护设计的简化计算具有一定的指导意义。

| Abstract: | Based on simplified Bishop method for stability calculation of slope, authors simplify stepped slope to slope with fewer steps or one step, and calculate the stability of simplified slopes. The results show that the calculated safety factor of original slope is very dosed to ones of simplified slopes, and the calculated critical sliding surfaces almost are in same place, so it can be concluded that the simplified calculation method of stability for stepped slope is feasible. The conclusion is of guiding importance to the simplified calculation for the support design of complex slope |
