摘　　要：城市的快速发展,使得基坑工程的项目由浅小基坑逐渐向深大基坑发展。在实际施工中,由于止水帷幕质量缺陷造成开挖漏水时,土颗粒将随渗流水被带出形成流砂,对基坑安全造成极大威胁,而现阶段在抢险处理上的经验较少。依托基坑工程实例,介绍了TRD工艺在止水帷幕失效情况下的应用,为类似的抢险处理提供施工经验。The rapid urban development has led to the gradual development of foundation pit projects from shallow and small pits to deep and large pits.In actual construction,when excavation leakage is caused by water-stop curtain quality defects,soil particles will be carried out with seepage water to form flowing sand,which poses a great threat to the safety of the foundation pit,and there is less experience in the emergency treatment at present stage.Based on the example of foundation pit project,the application of TRD process in the case of water-stop curtain failure is introduced to provide construction experience for similar emergency treatment.
