为了确保盾构安全穿越南京地铁二号线施工中遇到的地面废弃建（构）筑物遗留的桩基工程，就拔桩施工的机理、拔桩方法评价、套管钻进拔桩法施工工艺及施工机具选型与配套、施工效果以及施工中有关问题的探讨等作简单的介绍。所探讨的套管钻进拔桩法施工工艺简单、操作方便、施工效率高、施工效果好(尤其在近距离管线桩基的拔出)、费用低，可广泛在φ1000mm以内桩径、短桩、长弃桩拔除施工中推广应用。

Sleevedrilling pilepulling method is adopted in the construction of Line 2 of Nanjing Metro so as to ensure the safe boring of the shield machines when abandoned piles of surface structures are encountered. The mechanisms of pile pulling construction and the evaluation of different pile pulling methods are presented in the paper. The construction procedures, equipment selection and matching, construction results and problems of sleevedrilling pilepulling method are expatiated. The sleevedrilling pilepulling method focused in the paper is simple in procedures, easy in operation, efficient in construction, good in construction results and costsaving (especially for the case of pulling piles close to utility lines). The method can be widely applied in pulling of smalldiameter (diameter being less than φ1000mm) piles and short (length being less than 27m) piles.
