摘　　要：宣汉县渡口土家族乡立石村二组白岩湾(巴山大峡谷S201省道22 km处)高位山体发生危岩崩塌,造成在建工程损坏,掩埋既有省道,形成堰塞湖。结合区域地质背景和水文工程地质条件,查明崩滑体地质灾害特征,提出相应治理措施(坡面危石清除、河道清淤、省道改线、拦石墙及被动防护网工程),从而降低甚至消除崩滑体地质灾害风险,保障当地居民生命财产安全。A dangerous rock collapse occurred in the high-altitude mountain of Baiyanwan,group 2,Lishi village,Dukou tujia township,xuanhan county(22 km away from S201 provincial road in the Bashan grand canyon),causing damage to the ongoing construction project,burying the existing provincial road,and forming a barrier lake.Based on the regional geological background and hydrogeological engineering geological conditions,this paper identifies the characteristics of geological disasters caused by landslides and proposes corresponding control measures(such as slope rock removal,river dredging,provincial road rerouting,stone blocking walls,and passive protection network engineering),in order to reduce or even eliminate the risk of geological disasters caused by landslides and ensure the safety of local residents’lives and property.
