| 摘 要： | 采用非线形有限元数值模拟的方法,对岩质边坡开挖进行了数值分析。利用有限元软件ANSYS提供的单元生死功能模拟了重庆市某边坡锚杆挡墙工程逆作法施工的全过程,给出了其应力和变形的分布曲线,并对其应力和变形与未加锚时做了分析比较。算例表明,加入锚杆后边坡体上部水平位移分布曲线趋于平缓,在距坡脚约三分之一坡高的地方,比未加锚的水平位移值减少了15％。

| Abstract: | The excavation of the rock slope analysis was carried out by nonlinear FEM method in this paper. The rock slope was excavated with the reverse construction technique and retained wall with anchors. Processes were simulated with activating and killing elements provided by the FEM software of ANSYS. The FEM software of ANSYS gave the distribution curve of stress and deformation. Through this curve, the authors analyzed the stress and deformation for the condition of with and without supports. The results showed that the distribution curve of horizontal translocation became gentle in the top rock with anchors,the value of horizontal translocation reduced 15%. |
