摘　　要：云南省个旧重金属污染整治示范试验区建设过程中,由于场地开挖平整形成高陡岩质边坡,严重影响场区建设和运营安全。因此,需要对其进行稳定性分析,并提出相应的防治措施,为边坡永久治理提供依据。通过理正极限平衡法、Geostudio和FLAC3D数值模拟综合判定,天然工况下边坡整体稳定性均处于稳定状态,在暴雨工况和地震工况下边坡整体稳定性均呈不稳定状态。依据稳定性计算结果,将边坡防治划分为3个防治区段:重点防治区,主要防治措施为锚索框格梁+被动防护网;次重点防治区,主要防治措施为清危+框格锚杆;一般防治区,主要防治措施为清危+被动防护网,为边坡永久治理提供了依据。Yunnan province plans to build a demonstration and experimental zone for the treatment of heavy metal pollution in these old areas,and build,discharge and manage the small selection plants with small scale,low productivity and disorderly emissions that have been formed over the years.During the construction of the test area,the high and steep rock slope was formed due to the smooth excavation of the site,which seriously affected the construction and operation safety of the site.Therefore,it is necessary to analyze the stability of the slope and put forward the corresponding prevention and control measures,so as to provide a basis for the permanent treatment of the slope.According to the comprehensive judgment of the limit equilibrium method and the numerical simulation method,the overall stability of the slope is in a stable state under the natural condition,and the overall stability of the slope is in an unstable state under the rainstorm condition and the earthquake condition.According to the stability calculation results,the slope prevention and control is divided into three sections:the key prevention and control area,the main prevention and control measures are the anchor cable frame grid and passive protection net;Secondary key prevention and control area,the main prevention and control measures are clear dangerous and frame lattice bolt;General prevention and control areas,the main prevention and control measures for the clear dangerous and passive protection network.
