摘　　要：渗漏是水工混凝土建筑物最为常见的老化病害,渗漏源及渗漏通道的查找是解决渗漏问题的关键。针对辽宁某水库溢洪道堰面混凝土开裂并伴有渗水情况,通过钻孔观测基岩内水扬压力、全孔壁成像检查岩石裂隙发育状况及水质对比分析试验验证渗漏源,综合分析确定溢洪道基岩裂隙为主要渗漏通道,库区水是裂缝渗水主要来源。文章介绍的裂隙渗漏通道检测及渗漏源查找技术可供类似水利工程检测时参考和借鉴。Leakage is the most common aging problem for hydraulic concrete structure.Searching for leakage source and leakage passage is the key to solve leakage problem.In Liaoning,the surface concrete of a reservoir spillway weir was cracked and seepage.Based on the observation of uplift pressure in bedrock by drilling,the development of rock fracture examining by full bore wall imaging,and the water quality contrast analysis,this paper determined the bedrock fissure of spillway as the main seepage channel,and the reservoir water was the main source of fracture seepage by comprehensive analysis.The technique of leakage passage test and seepage source finding was introduced in this paper,which could be used for reference in similar water conservancy projects.
