坝基岩溶管道型涌水注浆封堵工程技术研究

Study on Grouting Plugging Engineering Technology of Karst Pipeline Water Gushing in Dam Foundation

由于岩溶地质的复杂性,坝基岩溶管道型涌水一直是水工领域的难点问题。以某水库大坝坝基岩溶管道涌水堵水治理工程为背景,基于压水渗透试验的坝基渗漏部位和原因进行分析,结合渗漏的实际情况,探讨坝基涌水注浆封堵工程技术思路,取得良好的工程堵水效果和经济社会效益,对相关类似工程具有重要的理论和实践借鉴价值。

Due to the complexity of karst geology,the karst pipeline water gushing of dam foundation has always been a difficult problem in the field of hydraulic engineering.In this paper,based on the water inrush and water plugging treatment project of a reservoir dam bedrock dissolution pipeline,the leakage parts and causes of the dam foundation are analyzed based on the pressure water seepage test.Combined with the actual situation of leakage,the technical ideas of the dam foundation water gushing grouting plugging engineering are discussed,and good engineering water plugging effect and economic and social benefits are obtained,which has important theoretical and practical reference for similar projects Value for reference.
