摘　　要：以广东某水库为例,综合分析封闭涵管渗漏特征初步找到渗漏原因,锁定渗漏排查范围,为快速堵漏提供基础。设计方案对渗漏通道采用砼混合物+钻孔灌浆进行防渗处理,加固效果明显,渗漏问题得到有效解决。Taking a reservoir in Guangdong as an example,a comprehensive analysis of the leakage characteristics of the closed culvert has preliminarily identified the causes of leakage and narrowed down the scope of leakage investigation,providing a basis for rapid leakage plugging.The design scheme employs a concrete mixture combined with borehole grouting for seepage control treatment of the leakage channels,resulting in significant reinforcement effects and effectively resolving the leakage problem.
