摘　　要：针对贵州拟建化工基地平场后形成的10个高边坡,通过运用Geo-Studio软件的SIGMA/W及SLOPE/W模块对边坡进行稳定性和变形计算,分析了开挖后的边坡在锚索加固支护前后的天然和暴雨工况下稳定性及其变形,研究了在未支护情况下边坡的最危险滑动面和变形以及锚索加固支护后的边坡稳定性。By using the SIGMA/W and SLOPE/W modules of Geo-Studio software to calculate the stability and deformation of the slope based on that about 10 high slope will be formed after the leveling of the chemical base to be built in Guizhou, the stability and deformation of the slope after excavation before and after the reinforcement and support of the anchor cable under natural and rainstorm working conditions are analyzed, and the determination and deformation of the most dangerous sliding surface of the slope under unsupported condition and the effect on the stability of the slope after reinforcement and support of the anchor cable are studied.
