道真县富强水库左岸岩溶发育特征及渗漏研究

A Study on the Characteristics of Karst Development and Leakage on the Left Bank of Fuqiang Reservoir in Daozhen County

富强水库修建于强岩溶发育地区,处于试蓄水阶段。本研究发现左岸有严重渗漏现象,通过大量的工程地质测绘、物探、钻孔、孔内电视、水文地质试验等手段,结合前期勘察及施工成果,研究了库区左岸岩溶发育规律和特征,查明了渗漏原因及范围,通过加深帷幕补强灌浆处理,将渗漏通道进行了封堵,取得明显防渗效果。

The Fuqiang Reservoir was built in areas with strong karst development and is in the stage of trial storage.This study found severe leakage on the left bank.Through extensive engineering geological surveying,geophysical exploration,drilling,borehole television,hydrogeological tests,and combined with previous surveys and construction results,the development laws and characteristics of karst on the left bank of the reservoir area were studied,and the causes and scope of leakage were identified.By deepening the curtain reinforcement grouting treatment,the leakage channel was sealed,achieving significant anti-seepage effects.
