摘　　要：我国西南地区地质构造复杂,岩溶发育,山地灾害暴发频繁,边坡失稳现象时有发生。本文以神奇制药沙文生产研发基地5#综合楼项目为例,经过软件计算得出西侧AB段、北侧BC段基坑边坡处于不稳定状态,采用排桩、锚索、格构、放坡等综合措施加固治理,运用FLAC3D 6.00软件模拟基坑开挖的全过程,开展基坑边坡开挖后的变形破坏机理、稳定性分析及加固治理研究,可为防治减灾提供借鉴。The geological structure in southwest China is complex,with developed karst and frequent mountain disasters.Therefore,slope instability occurs from time to time.In this article,the 5#comprehensive building project of Miracle Pharmaceuticals Shaven Production R&D Base was taken as an example.After calculation by software,it was found that the AB section on the west side and of the BC section on north side of foundation pit slope were unstable.Comprehensive slope reinforcement measures such as row pile,anchor cable,lattice structure,and grading were used.The entire process of foundation pit excavation was simulated using FLAC3D 6.00 software.It is of great significance to carry out research on the deformation and failure mechanism,stability analysis and reinforcement treatment after excavation of foundation pit slopes,and it can provide engineering reference for disaster prevention and reduction.
