摘　　要： 里洪水库大坝坝体填土中因砾石含量较大,填土压实度、透水性不满足规范要求,导致坝基及坝肩存在渗漏问题。介绍了高压摆喷灌浆工艺在主坝防渗中的应用及施工工艺。通过高压摆喷灌浆后形成了连续板式防渗墙,有效地解决了土坝坝体及坝基渗漏问题。 Lihong Reservoir is designed with an earth dam.The filled earth has high gravel content,with the compaction degree and water permeability not up to requirements of standard,which led to seepage at dam foundation and abutment.An introduction was made on the application of high pressure swing grouting in seepage prevention of main dam and the construction technique.Continuous slab cutoff wall was constructed after grouting,effectively solving the seepage problem.
