摘　　要：田湾河流域仁宗海水库电站挡水大坝为深厚覆盖层地基,覆盖层结构层次复杂,坝基第⑦层承载力低,不能满足坝基承载、变形及坝坡抗滑稳定要求。介绍了振冲碎石桩在仁宗海坝基第⑦层淤泥质壤土处理中的应用。复合地基检测和坝基稳定性复核计算结果表明,堆石坝坝基淤泥质壤土加固处理满足设计技术及现行规范要求。Tianwan river basin Renzonghai renzonghai reservoir station retaining dam is a deep overburden foundation, overburden structure has complex arrangement, and the seventh layer of the dam foundation has low bearing capacity, and can not meet the requirement of dam foundation bearing, deformation as well as dam slope anti-skid stability. The paper describes the application of vibro replacement stone column in the seventh layer of Renzonghai dam foundation. The result of the treated composite foundation test and dam foundation ability rechecking calculation showed that the silt loam reinforcement treatment on rockfill dam foundation of Renzonghai power station is in line with the requirements in design technique and current standard.
