摘　　要：峡江水利枢纽工程一期枯水围堰防渗工程采用高喷防渗技术,针对工程具体情况,确定全断面采用高喷防渗,并通过生产性试验确定施工参数.本文介绍了施工中出现的异常现象、影响高喷质量的重要部位和关键工序的施工控制方法,并通过基坑排水、钻孔取芯和探坑开挖检查,验证了高喷防渗效果的有效性.The anti-seepage engineering of a low water cofferdam of Xiajiang Hydro-junction Project adopted the technology of high-pressure jet grouting.Based on the concrete condition of this project,the whole section anti-seepage engineering adopted the high-pressure jet grouting.The construction parameters is determined by the construction experiment.The abnormal phenomenon in the construction,the important parts of influencing the quality of high-pressure jet grouting and the construction control method of key process are introduced.The anti-seepage effect of high-pressure jet grouting is verified by the excavation drainage,taking rock core by drilling and the excavation checking of test pit.
