摘　　要：天津某平原水库围堤底部无连续的相对隔水层,渗漏通道密集,经过30 a的运行,出现较为明显的渗漏问题。项目采用40 m深高压喷射防渗墙对围堤进行加固,通过优化浆液配比,保证了深层高压喷射防渗墙的整体性与稳定性。根据有限元数值分析及运营期监测数据分析,加固措施可有效减少水库渗漏量,验证了方案的可靠性,对类似工程具有重要的借鉴意义。In a plain reservoir in Tianjin,there is no continuous relative impermeable layer at the bottom of the embankment,and the leakage channels are dense.After more than 30 years of operation,there has been a relatively obvious leakage problem.In the project,the embankment adopted was reinforced with a deep high-pressure jet anti-seepage wall nearly 40m.By optimizing the slurry ratio,the integrity and stability of the deep high-pressure jet anti-seepage wall were ensured.According to the finite element numerical analysis and monitoring data analysis during operation,the reinforcement measures could effectively reduce reservoir leakage,verifying the reliability of this plan.It has important reference significance for similar projects.
