锦屏一级水电站左坝肩边坡岩体质量CSMR分类

Application of the CSMR system to slope stability evaluation for Jinping First Cascade Hydropower Station

系统地介绍边坡岩体质量评价分类的 CSMR 法,结合锦屏水电站左坝肩边坡工程的实例,根据结构面性质的不同细化了结构面修正系数,并引入了结构面连通率,对 CSMR 分类进行了修正。分析结果表明,修正后的 CSMR 分类更加合理。

The CSMR method of slope rock mass quality evaluation is introduced with a practical example of the left abutment slope at the Jinping First cascade Hydropower Station.The system has been amended by refining the compensation factor of rock discontinuity structure and introducing its connectivity rate.It is proved that the method is practicable.
