盖下坝水电站右岸坝后危岩体稳定分析

摘要

There is a dangerous rockmass in the right bank of the Gaixiaba Dam. The rockmass has a height of about 240 m,maximum thickness of 10 m, maximum width of 130 m and total volume of about 0.25 million m3. Based on the engineering geological studies, the stability of the roekmass is qualitatively and quantitatively evaluated. The analysis provides a reliable basis for the roekmass treatment.%盖下坝水电站坝址右岸存在高约240m,最大厚约10 m,最大幅宽130 m的危岩体,总体积约25万m3.在对盖下坝水电站坝址右岸边坡危岩体主要工程地质问题分析的基础上,对其稳定性进行了计算分析,从而定性定量地对其稳定性做出评价,为工程处理方案提供了可靠依据.
