摘　　要：佛山口腔医院迁建工程项目深基坑三轴止水帷幕因地质条件、施工质量等因素,个别部位止水帷幕没能很好地连接形成整体,在开挖过程中出现渗漏现象。考虑项目地为河床旧址,渗漏点位于粉砂层,遂使用坑外双液注浆加坑内棉絮隔砂及土方反压等措施进行修补,经实践此套措施效果显著。Due to geological conditions,construction quality and other factors,some parts of the water stop curtain can not be well connected to form a whole,and leakage occurs in the process of excavation.Considering that the project site is an old riverbed site and the leakage point is located in the silty sand layer,measures such as double liquid grouting outside the pit,cotton wool sand separation inside the pit and earthwork reverse pressure are used to repair the project.The practical results of these measures are remarkable.
