摘要
根据现场地质勘察报告,利用Bishop条分法对案例边坡项目的稳定性进行分析,确定了边坡在天然工况下和暴雨工况下的安全系数分别为0.751、0.648,均小于规范要求的安全系数标准值1.00,说明该边坡稳定性较差.基于边坡稳定性分析结果,从施工安全性及经济性两方面对锚拉式桩板挡墙和排桩式锚杆挡墙支护方案进行对比优选,确定排桩式锚杆挡墙为边坡支护方案.
Abstract
According to the site geological investigation report,study analyzes the stability of the slope project in the case with Bishop's segmentation method,and determines that the safety factors of the slope under natural conditions and rainstorm conditions are 0.751 and 0.648 respectively,both of which are lower than the standard value of 1.00 required by the code,indicating that the stability of the slope is poor.Based on the results of slope stability analysis,the bolting schemes of bolting pile retaining wall and bolting pile retaining wall are compared and optimized from construction safety and economy,and bolting pile retaining wall is determined as the bolting scheme of slope.
