摘　　要：以腾龙桥二级水电站大坝左岸HP1滑坡体为研究对象,对工程滑坡进行了全面的分析研究。腾龙桥二级水电站为坝后式水电站,厂房紧接在大坝后面,位于HP1滑坡对面,整个枢纽布置比较紧凑。HP1滑坡规模大,距离厂房和大坝较近。对电站左岸滑坡的成因及影响因素和处理方案作了客观、科学和全面的探索与研究,采用刚体极限平衡法和有限元法对滑坡进行稳定分析计算,根据计算成果及电站工程技术各方面的要求对滑坡加固方案进行了研究和设计,提出两种处理方案进行对比,最终提出了预应力锚索和抗滑桩联合使用的加固处理措施,最终完成了电站的滑坡处理工作。Taking the HP1 landslide mass on the left bank of the dam of tenglongqiao II hydropower station as the research object,the engineering landslide is comprehensively analyzed and studied.Tenglongqiao II hydropower station is a post dam hydropower station.The powerhouse is located behind the dam,opposite to HP1 landslide.The layout of the whole project is relatively compact.HP1 landslide has a large scale and is close to the powerhouse and dam.This paper makes an objective,scientific and comprehensive exploration and research on the causes,influencing factors and treatment scheme of the landslide on the left bank of the hydropower station.The stability analysis and calculation of the landslide are carried out by using the rigid body limit equilibrium method and the finite element method.According to the calculation results and the requirements of various aspects of the power station engineering technology,the landslide reinforcement scheme is studied and designed,and the two treatment schemes are compared and finally proposed Finally,the landslide treatment of the power station is completed by the reinforcement measures of prestressed anchor cable and anti-slide pile.
