摘要
针对强岩溶发育地区筑坝建库中坝基渗漏的问题,笔者结合大茅坡水库在试蓄水过程中,面板堆石坝坝基由于岩溶发育出现的大流量渗漏,分析了坝基渗漏的原因,并根据渗漏检测试验结果制定了补强帷幕灌浆的防渗处理方案。灌浆实施后的运行监测结果表明,水库运行情况良好,未发现异常的坝基渗漏,说明渗漏处理效果较好。该大流量渗漏处理的思路为类似问题的处理及类似工程的设计施工提供借鉴和参考。
In view of the problem of dam foundation seepage in dam construction in strong karst areas, the author analyzes the causes of dam foundation seepage based on the large flow seepage caused by karst development in the dam foundation of Damaopo Reservoir during trial impoundment, and formulates the anti-seepage treatment scheme of reinforcing curtain grouting according to the test results of seepage detection. The operation monitoring results after grouting show that the reservoir operates well and there is no abnormal dam foundation leakage, indicating that the leakage treatment effect is good. The idea of large flow leakage treatment provides reference for the treatment of similar problems and the design and construction of similar projects.
