| 摘 要： | 针对河南省济邵高速公路的王坑隧道洞口滑坡问题,采用极限平衡法和有限元法对其稳定性进行了评价.计算结果表明:该滑坡达不到稳定性要求,必须进行加固处理.根据滑坡的实际情况,采用抗滑桩结合地表排水对滑坡进行治理.利用有限元法对滑坡体治理后的稳定状况进行分析,并与滑坡体治理前的稳定状况进行对比.结果表明:抗滑桩加固方案能够达到滑坡治理的设计要求.

| Abstract: | The study of landslide stability at the portal of the Wangkeng tunnel was conducted in terms of four kinds of loading conditions using the limit equilibrium method and FEM.Based on the results of stability analysis,the anti-slide piles and ground drainage were adopted to control the landslide.A comparative study using FEM showed that the control measures adopted met the design specifications. |
