摘　　要：在高层或超高层建筑施工中,为了防止后期沉降所产生的裂缝,按照设计和施工的相关要求,需要在基础板墙梁等相应的位置上面进行施工后浇带。后浇带设置,削弱了地下室阶段结构整体受力,在基坑内支撑换撑拆除过程中,如何保证拆撑后后浇带位置结构安全尤为重要。结合在施项目的工程的实际,阐述了深基坑内支撑拆除,后浇带位置使用传力杆的施工方法。In construction of high-rise or super-high-rise buildings,in order to prevent cracks caused by later settlement,according to relevant requirements of design and construction,it is necessary to carry out post-pouring belts on the corresponding positions such as foundation slabs,walls and beams.The setting of the post-pouring belt weakens overall force of the basement stage structure.In the process of support replacement in the foundation pit,how to ensure safety of the post-pouring belt position and structure after the support is removed is particularly important.Combined with actual construction of the project,construction method of the support removal in the deep foundation pit and use of the transfer rod at position of the post-pouring belt is explained.
