摘　　要：南京地铁二号线一期工程废弃桩拔桩施工中,根据拔桩施工的工作机理及拔桩过程中的断桩原因和处理方法,采用套桩成孔减摩法和钢丝绳套断桩法相结合的方案,不受桩的形式和桩径限制,实践证明该法效果较好。During extracting construction of abandoned piles in Nanjing subway line 2 phase I engineering, lagging pile pore forming antifriction method and steel wire lagged broken pile method are adopted according to the working principle of pile extracting construction, pile breaking reason and treatment method during pile extracting. The methods are not limited by the form and diameter of pile and it has been proved in practice that they have favorable effect.
