摘　　要：某水库大坝经安全评价,评定为“三类坝”。大坝主要存在的问题是坝体渗透稳定性较差,存在渗流安全隐患。为确保水库安全运行,需采取有效防渗措施进行安全加固,以保证水库安全运行。经几种防渗处理方案的对比分析,拟采用深层水泥土搅拌桩防渗墙作为坝体的防渗技术措施。加固施工完成后通过4种检测手段对防渗墙实际质量进行检测,结果表明:水泥土搅拌桩防渗墙可较好地解决坝体渗漏问题。A certain reservoir dam has been evaluated for safety and is classified as a"Class III dam".The main problem with dam is its poor seepage stability and potential safety hazards.To ensure the safe operation of the reservoir,effective anti-seepage measures need to be taken for safety reinforcement to ensure the safe operation of the reservoir.After comparing and analyzing several anti-seepage treatment schemes,it is proposed to use deep cement soil mixing pile anti-seepage wall as the anti-seepage technical measure for the dam body.After the reinforcement construction is completed,the actual quality of the anti-seepage wall is tested through four testing methods.The results show that the cement-soil mixing pile anti-seepage wall can effectively solve the problem of dam leakage.
