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.
