摘　　要：以楸树湾铜钼矿为例,根据边坡勘察结果,通过GeoStudio软件模拟分析其边坡不同降雨模式的渗流场,确定边坡稳定性情况,并设计针对性的桩锚支护方案,即旋挖灌注桩+预应力锚杆对边坡进行支护,最终经验证相同预应力下,该桩锚支护方案的稳定系数要优于传统支护方案,证明旋挖灌注桩+预应力锚杆支护技术在矿山边坡支护中有着良好的应用价值。In this paper,Qiushuwan copper molybdenum Mine is taken as an example.According to the slope investigation results,GeoStudio software is used to simulate and analyze the seepage field of the slope in different rainfall modes to determine the stability of the slope,and a targeted pile-anchor support scheme is designed,that is,rotary cast-in pile+prestressed anchor bolt to support the slope.Finally,under the same prestressed stress,the stability coefficient of the pile-anchor support scheme is better than that of the traditional support scheme,which proves that the technology of rotary excavation cast-in-place pile and prestressed anchor bolt has good application value in the mine slope support.
