摘　　要：针对超深基坑(挖深超过15m的基坑)由于受地压、土性、设备性能、施工控制技术等影响而导致围护结构防渗控制相对较难的情况,以南京地铁1号线珠江路车站工程为背景,基于对超深基坑SMW围护结构渗水原因的分析,从理论上对防渗墙的厚度及墙体的变形进行设计计算,并从施工的角度对防渗控制技术进行了探讨.In consideration of some affecting factors, such as the earth pressure, soil characteristics, equipment performance, and construction control techniques, it is relatively difficult to control seepage through curb walls with ultra-deep foundation pits (the depth being over 15m) during the construction period. Based on an analysis of the causes of seepage through the curb wall structure, the thickness and deformation of the impervious wall were determined for the design of the Zhujiang Road Station in the Nanjing metro project, and the seepage control technique was also discussed from the angle of construction.
