| 摘 要： | 利用大型有限元分析软件,考虑岩土变形的影响,采用完全弹塑性模型,Drucker-Prager屈服准则以及边坡最大水平位移增量与材料强度折减之比达到极值作为边坡破坏的标准,对锚杆加固边坡的稳定性进行了分析,得到了边坡稳定系数,并利用临界破坏状态时边坡的等效塑性应变图来确定潜在滑动面,为工程设计提供了参考依据.

| Abstract: | Using large-scale finite element analysis software,to consider the impact of rock deformation,full-plastic model,Drucker-Prager yield criteria,using the largest increase the level of displacement and material strength reduction ratio to achieve maximum to slope damage as the standard,the anchor reinforced slope stability is analysed and the factar of archiving slope stability is obtained.The map of equivalent plastic strain of critical damage slope is use to determine the potential sliding surface.The resul... |
