摘　　要：TRD止水帷幕是一种新型的具有优良防渗功能的水泥土介质,在防治基坑渗流的工程实践中取得了良好的效果。以贵州某岩溶富水区基坑施工为背景,介绍了TRD止水帷幕技术在岩溶区临河特长深基坑中的应用。首先通过现场成墙试验确定了TRD止水帷幕在该地区的施工参数以指导实际施工,并监测了TRD止水帷幕施工对周边环境的影响。对施工工序进行了详细介绍并对施工要点进行了总结。TRD cut-off curtain is a new type of waterproof cement soil medium which has excellent anti- seepage function, it achieves good results in the practice of foundation excavation engineering of preventing and controlling the seepage. Taking the construction of a foundation excavation in Karst area with rich water in Guizhou as background, this paper introduces the application of TRD cut-off curtain method in deep and long foundation excavation. First, through the field test of wall construction, the parameters of TRD curtain were determined, then the influence of TRD construction on the surrounding environment was monitored. And the construction procedure is introduced and the main points of the construction are summarized.
