| 摘 要： | 通过大量现场调查和综合分析，对西南某水电站闸址区两岸高边坡的变形破坏类型、破坏特征、影响因素及变形破坏机制等进行了深入研究，认为该区岩体的变形破坏模式主要有滑移-拉裂型、弯曲-拉裂型及剥落、剥离或拉裂倾倒型3种，因而引起岩体产生崩滑、弯曲倾倒及剥落、剥离或拉裂倾倒破坏，在此基础上，对其可能给闸址工程安全带来的影响进行了评价。

| Abstract: | Based on systematic field survey and comprehensive analyses, the types, characteristics, influencing factors and mechanism of the deformation and failure of high slopes, located in two sides in the lock site region of a hydropower station in southwest China, were investigated. The research shows that there are three types of the deformation and failure model of rock mass, they are sliding-fracturing, bending-fracturing, and flaking-peeling or fracturing-toppling. Therefore, there is a possibility for rock mass to generate the failures of falling and sliding, bending and toppling, and flaking and peeling or fracturing and toppling. Based on the above results, potential influence on the project was evaluated. |
