乌江洪家渡水电站厂坝基坑岩溶涌水与处理

Treatment of karst water gushing in foundation pitof Hongjiadu hydropower station on Wujiang PAver

在岩溶区兴建水力发电工程，基坑岩溶涌水是主要工程地质问题之一。乌江洪家渡水电站为在岩溶区兴建的大型水力发电工程，基坑内发育有K40、K80—1等岩溶管道系统，基坑岩溶涌水问题突出，现工程已完建，基坑岩溶涌水问题得到了成功处理。本文就乌江洪家渡水电站基坑岩溶涌水预测及工程处理进行总结、介绍。

Water gushing of foundation pit is one of the main engineering geologic problems for the hydropower projects built in karst area. Hongjiadu hydropower project is a large - scale hydropower project built in karst area. The problem of K40 and K80 - 1 path system in the foundation pit and water gushing is evident. At present, the project has been completed and the karst water gushing problem in foundation pit has been treated successfully. The paper concludes and introduces the forecast and engineenng treatment of karst water gushing in foundation pit of Hongjiadu hydropower station.
