水布垭水电站运行期地下厂房渗水分析与处理

Analysis and Treatment of the Water Leakage Problem in Underground Powerhouse of Shuibuya Hydropower Plant during Operation Period

针对水布垭水电站运行期地下厂房出现的渗水情况,结合厂房结构、内外防渗设计、泄洪及强降雨检查情况等方面,对渗水原因综合、系统分析,提出相应处理措施,实施后经主汛期强降雨及泄洪检验,厂房渗水问题得到了有效解决。

Excessive water leakage is observed in the underground powerhouse of Shuibuya Hydropower Plant during operation period.Considering the powerhouse structure,internal and external seepage control design,inspection situations during the flood discharge and heavy rainfalls,possible reasons of the water leakage problem are analyzed comprehensively.Treatment measures are then proposed correspondingly.Practical tests of heavy rainfalls and flood discharge in the main flood season show that the leakage problem of the powerhouse is effectively solved.
