摘　　要：大型水电站库区不仅容易诱发地震,还易产生不同程度的滑坡。滑坡的产生往往伴随着连续降雨天气,提前预防可以有效减小损害。该文以实际滑坡体为工程背景,结合区域水文地质条件及监测数据,现场地表及深部位移变形为之验证,分析水电站库区滑坡的成因机制及形成机理。结果表明,水库塌岸是滑坡体产生变形的一个诱因,长期降雨是诱发滑坡形成的主要影响因素。为滑坡预防及治理提供一定的借鉴。The reservoir area of large hydropower stations is not only easy to induce earthquakes,but also easy to produce different degrees of landslides.The occurrence of landslides is often accompanied by continuous rainfall,and prevention in advance can effectively reduce the damage.Taking the actual landslide as the engineering background,based on the regional hydrogeological conditions and monitoring data,and the on-site surface and deep displacement and deformation,this paper analyzes the genetic mechanism and formation mechanism of landslides in the reservoir area of hydropower stations.The results show that the bank collapse of the reservoir is an inducement of the deformation of the landslide,and the long-term rainfall is the main factor inducing the formation of the landslide.It can be used as a reference for landslide prevention and treatment.
