摘要
针对杭州至兰州高速公路巫山—奉节的A20标K54+010~+150段,由于开挖路堑边坡引起的工程滑坡,在对滑坡的发展过程及变形破坏特征等进行调查研究的基础上,分析了产生滑坡的原因,并提出了清方卸载、排水和抗滑桩等综合处治措施。工程实践证明,坡体稳定,社会经济效益效果较好。
Against Wushan-Fengjie Section A20 marking K54+010~+150 of Hangzhou-Lanzhou Highway,engineering landslide is caused by cutting slope.Based on the investigation and study of landslide development and characteristics of deformation failure,the reasons causing landslide are analyzed and the comprehensive treatment measures including clearing,unloading,draining and friction pile are proposed.The engineering practice proved that the landslide body is stable and the social and economic benefits are good.
