| 摘 要： | 以现场地质勘查及室内试验研究成果为基础,采用有限元软件模拟了构皮滩水电站第三级升船机边坡的开挖施工过程,通过对比分析三种不同支护开挖方案条件下边坡的变形形态、最大主应力分布及塑性区分布规律,研究了边坡的开挖稳定性,得到以下结论:锚杆和锚索的支护方案能有效控制局部失稳区域的位移变形形态;锚杆和锚索支护方案能有效控制边坡坡面开挖后的拉应力区;锚杆、锚索支护均能有效控制边坡开挖后的塑性区面积及分布;锚杆和锚索同时施加的支护方案能较好的保障第三级升船机边坡的开挖稳定性。 |

| Abstract: | Based on the field geological exploration and the laboratory tests,a finite element analysis for the excavation stability was conducted on the ship lift slope of Goupitan Hydropower Plant.The deformation,the maximum principal stress distribution,and the failure zones of three different excavation schemes were studied.It is found that the deformation,the zones of tensile stress and zones of potential failure can be effectively reduced by the proposed rock anchors.The stability of the ship lift slope can be assured throughout the detailed analyses. |
