摘　　要：灰岩地区一般溶洞较多,采用桩基(如冲抓桩)时,常会出现护桩泥浆塌陷、漏失现象而不能正常浇砼。该文工程实例中,对岩溶地区某工程采用冲抓桩出现护桩泥浆漏失现象进行了分析,并对桩位处的溶洞进行灌浆处理,施工结果表明处理效果良好。Because of a lot of caves in limestone area, when taking percussion and grabing piles as foundation there often occured grout collapse and leakage, therefore normal grouting can not be conducted. In the paper taking engineering project as an example to analyse grout leakage in Karst area by using percussion and grabing pile and conduct grouting treatment at pile position, the results showed that it is useful.

关 键 词：灌浆法 泥浆漏失 溶洞 充填灌浆
