摘　　要：水库渗漏问题较为复杂,详实的地质资料是分析渗漏问题的基础。本文以广西冷冲水库为例,查明坝基存在断层破碎带,综合分析水库渗漏特征找到了集中渗漏通道,为设计提供可靠的依据。设计方案对渗漏通道采用高压旋喷灌浆+充填灌浆进行防渗处理,加固效果明显,渗漏问题得到有效解决。The problem of reservoir leakage is complicated and detailed geological data is the basis of analyzing the problem.Taking Lengchong Reservoiy in Guangxi as example,the authors present how to identify the fault fracture zone in dam foundation and find out the concentrated leakage channel through comprehensive analysis of the reser-voir leakage features which provides reliable basis for design.The treatment scheme incorporates high pressure rota-ry spray grouting with filling grouting.The reinforcement effect is obvious and the leakage problem is effectively solved.
