摘要
贵州乌江洪家渡水电站于2004年6月下闸蓄水,当水库蓄水位到达1100m(设计正常蓄水位1140m)附近时,库岸陆续出现塌岸、滑坡等不良地质现象。其中硬质岩库岸危岩体稳定性问题也日趋突出,特别是大型危岩体失稳入库产生的涌浪问题,一直是同行们关注和感兴趣的研究课题。本文以洪家渡水电站库区文昌阁危岩体为例,对其稳定性及失稳入库后产生的涌浪进行预测,以期为同类工程的稳定分析、涌浪预测分析提供参考。
When water level of Wujiang Hongjiadu Reservoir was up to 1100m （normal level is 1140m）, some bad geological appearances such as bank landslide, collapse and etc. occur one after another. Among them the stability of dangerous rock mass on the hard band is noticeable, because surge will be produced when it falls down into the reservoir. Using Wenchangge dangerous rock mass in reservoir area as example, the writer forecasted the surge when it falls down into the reservoir. The result could be as reference for stable analysis and surge forecast of other similar projects.
