摘要
通过总结宝兴水电站进水口边坡稳定性分析和治理的成功经验,简单介绍了由破碎岩体构成的特殊岩质边坡稳定性分析和治理的方法和措施。该边坡由块状结构的破碎岩体组成,它的破坏既不属于顺层滑动,也不同于结构面组合滑动或反坡向倾倒、崩塌等,与滑坡的最大区别在于无统一的滑动面。对该边坡的稳定性分析,首先在进行工程地质分区的基础上,确定了潜在的滑移边界,采用GEO-SLOPE计算程序进行反演分析,最终确定最危险滑移面,根据岩体和结构面的特性选取参数进行了稳定性计算。通过计算结果,确定了较为合理、可行、可靠的治理方案,取得了良好的效果。
Through the successful experience on the Stability analysis and reinforcement for intake slope of Baoxing hydropower station,This article simply introduced the method how to research on the Stability analysis and reinforcement of special rock slope constituted by cataclastic rock. This slope is neither belong to bedding slip, nor sliding by association of structural plane or overturn in counter-inclined structure, the biggest difference of landslide is the slope have not the uniform slip face. Stability analysis on this slope, The writer firstly defined the potential slip face, and use Geo-slope for inversion analysis, finally determine the most dangerous slip face, and choose parameters which based on the characters of rockmass and structural plane to calculate the stability. Rely on the result of calculation, obtained good effectiveness by the proper, feasible, credible reinforcement.
