采用边坡稳定分析的非线性有限元混合解法对索风营水电站Dr2危岩体的稳定性进行了分析,即由强度折减法搜索其可能滑动面,确定危岩体最可能的破坏方式和滑动面位置,然后重新建立模型,加入搜索得到的滑动面和加固措施,由有限元迭代解法求得其滑动面的安全系数.通过该法确定了Dr2危岩体最危险滑动面,并计算得到了每项加固措施对危岩体抗滑稳定安全性的贡献度,为加固措施的优化提供了一个很好的参考依据.

The stability of the Dr2 endangered rock mass of the Suofengying Hydropower Plant was analyzed using the mixed non-linear finite method for analysis of slope stability. Firstly, the strength reduction method was employed to search for the potential slip surface so as to determine the most likely failure mode and position of the slip surface of the endangered rock mass. Then, a new model was established, and the slip surface and reinforcement measures were introduced into it. The safety factor of the slip surface was obtained with the finite element iteration method. Using the proposed method, the most dangerous slip surface of the Dr2 endangered rock mass was determined, and the contribution of every reinforcement measure to the stability safety factor of the slip surface was quantified, providing a good reference for the optimization of the reinforcement measures.
