湖南新田水浸窝水库渗漏分析及其治理

水浸窝水库是采用全封闭式堵洞而成的地下、地表水库。其渗漏类型按渗漏及出流状况分,属于集中管道渗漏、集中管道式出流;以渗漏场在水库中所处的地貌部位分,属于近坝库岸渗漏类型(坝下渗漏)。解决该水库渗漏的最佳方案是在原坝址上游83. 0m处修建新坝并辅以适当的帷幕灌浆处理。该处工程地质条件好,无需清基,坝前有天然通气孔,经济安全。 

ANALYSIS ON THE LEAKAGE MECHANISM AND THE TREATMENT METHOD FOR SHUIJINWO RESERVOIR IN XINTIAN COUNTY, HUNAN PROVINCE

The Shuijinwo reservoir is a completely closed reservoir built in a cave and it is composed of above-ground part and underground part. According to the conditions of leakage and flow, the leakage type is divided into concentrative pipe leakage and concentrative pipe flow. According to the geomorphic location in the reservoir, the leakage type belongs to near-dam leakage from reservoir, namely seepage through dam foundation. The best way to solve the leakage is to build a new dam in a about 83.0m upstream of the original dam and lend support to with appropriate of treatment by curtain grouting. The geological condition of the site is prefect and does not need base disposal, furthermore, there is natural vent hole before the dam. So it is economical and safe.
