摘　　要：在喀斯特地区,水库岩溶渗漏严重影响着水库安全。笔者结合工程实例,通过工程地质勘察查明库区渗漏的形式和分布范围,经论证后提出了切实可行的防渗处理方案。针对防渗处理过程中出现的岩溶发育情况,采用高密度电法、孔内摄像等物探手段查明岩溶通道发育规模及性质,并提出采用自密实混凝土对岩溶通道进行封堵。现场观测结果表明,防渗处理达到了预期效果。自密实混凝土可在岩溶渗漏处理中推广应用。In karst areas karst leakage in reservoirs seriously affects the safety of reservoirs.Based on an engineering example the authors identify the form and distribution range of leakage in the reservoir area through engineering geological investigation and put forward a feasible anti-seepage treatment scheme after demonstration.In view of the karst development in the process of anti-seepage treatment geophysical prospecting methods such as high-density electrical method and borehole camera are used to find out the development scale and properties of karst channels and self-compacting concrete is proposed to block karst channels.The field observation results show that the anti-seepage treatment has achieved the expected effect.Self-compacting concrete can be applied in karst leakage treatment.
