摘　　要：“清泉洞”穿越坝体，是大坝工程隐患，搞清楚“清泉洞”的补给水源是库水补给，还是原地下水补给，是除险加固方案成败的关键。通过工程地质勘察和稳定同位素研究认为，“清泉洞”水是库水经过左岸玄武岩裂隙、淤积层及坝体渗透补给，采取针对性的措施，实践证明效果显著。The 'Qingquan culvert'crosses the dam body . It is a hidden danger of the large dam project . To make sure whether the recharge water source of 'Qinquan Culvert ' is the reservoir water or the original groundwater being the key problem of success or failure of the scheme for its anti-hazard and strengthening. By engineering geological investigation and stable isotope study , it is considered that the 'Qingquan culvert 'water is recharged by the reservoir water passing the basalt fissure and the mucky soil layer at the left bank and the seepage water through the dam body . Measures aiming at this recharge condition are adopted , the engineering practice proves that the effects are obvious.
