清江干流水布垭水电枢纽是与隔河岩、高坝洲水电枢纽并重的国家级大型水电工程 ,坝址区高边坡稳定性问题是水布垭坝址主要的工程地质问题之一。采用三维有限元数值模拟方法 ,对坝址区岩体应力场和位移进行了研究 ;探讨了岩体三维应力、应变分布与岩体变形破坏的关系 ,评价了岩体的稳定性
The Shuibuya Hydroelectric Power Station of the Qingjiang River is a national large-scale hydropower project with emphasis on Geheyan and Gaobazhou hydropower hubs. The stability of high slope in the dam site is one of the major engineering geological problems of the Shuibuya Dam site. The stress field and displacement of rock mass in dam site are studied by using 3D finite element numerical simulation method. The relationship between three-dimensional stress and strain distribution of rock mass and deformation and failure of rock mass is discussed, and the stability of rock mass is evaluated
