摘　　要：本文结合南京长江隧道梅子洲岸边段抗拔桩的工程设计实例,对软弱地层中抗拔桩的设计方法作了一个探讨。笔者提出在软弱地层中,抗拔桩应在高水位时能保证抗浮的要求,低水位时能兼做承压桩满足桩基承载力的要求。本文提出的设计方法在实际工程设计中得到应用,并可为相关工程提供一定的参考。In low water level, the uplift piles in soft ground maybe change to pressure piles. In the design of uplift piles in soft ground, the uplift piles should ensure the requirements of anti-floating in the high water level, and they also must achieve the demand of the carrying capacity in the low water level. The design method was used in the design of uplift piles in Meizizhou open-cut tunnel of Nanjing Yangtze River Tunnel, and it can also be adopted for similar projects.
