| 摘 要： | 为了对边坡稳定性分析方法进行研究，以某场地高填方边坡和直立边坡为研究对象，基于Geostudio、理正软件以及ANSYS软件，采用M-P法、Bishop法和强度折减法进行边坡稳定分析。结果表明:高填方边坡安全系数为1.3，为稳定边坡；AB，BC，CD段地块间边坡边坡安全系数依次为0.479，0.410，0.381，基坑边坡安全系数为0.436，均为不稳定边坡；其中，M-P法得到的安全系数偏保守，Bishop法得到的安全系数结果较可靠，强度折减法得到的结果最为理想。研究结果可为边坡稳定性研究与治理提供借鉴。

| Abstract: | In order to study the slope stability analysis methods,the High Fill Slope and Vertical Slope of a site are taken as the research objects.Based on Geostudio,Lizheng and ANSYS software,M-P Method,Bishop Method and Strength Reduction Method are used for slope stability analysis.The results show that the Safety Factor of High Fill Slope is 1.3,which is a stable slope ; the Safety Factors of Landmass Slopes in AB,BC，CD sections are 0.479,0.410，0.381 respectively,which are all unstable slopes.The Safety Factor of foundation pit slope is 0.436,which is unstable slope.Among them,the Safety Factors obtained by M-P Method are conservative,the Safety Factors obtained by Bishop Method are reliable,and the Strength Reduction Method is the most ideal.The research results can provide reference for slope stability research and control. |
