摘要
在查明金沙江乌东德水电站库区基本地质条件的基础上,对岸坡地质结构特征进行了总结,分析了库岸崩塌、滑坡的分布特征,并对崩塌、滑坡现状及蓄水后稳定性进行了分析。根据以上岸坡地质结构特征及库岸变形破坏特征,在对岸坡地质结构进行分段的基础上,对库岸稳定性作出分类评价。分类结果表明,库区主要为岩质岸坡,稳定和基本稳定的库岸长度约占总长度的65%。
We first explore the basic geological condition at dam site area of Wudongde Hydropower Station, and then summa- rize the geological structures characteristics of bank slope. The geological disasters distributions along the reservoir bank such as bank collapse, landslides are analyzed and their development tendency after reservoir impoundment is evaluated. Based on the characteristics analysis on geological structure and bank slope failure, the bank stope stability condition is categorized. The cate- gorized analysis results show that the rock slope is predominant in the reservoir area, the length of stable and basic stable bank slope consist of 65% of the total bank section.
