摘　　要：南京德基广场二期工程是目前国内规模最大的逆作法工程之一,地下5层、地上62层。该工程裙楼采用逆作法施工,利用地下连续墙围护、结构梁板作为水平支撑,工程地下室结构与基坑土方开挖交叉流水进行;土方开挖以明挖、盖挖结合实施,是工程总体部署的关键工序。结合工程实际与设计要求,介绍土方开挖采用"分层、分区、对称、流水"的施工方法,基坑土方开挖与地下室结构施工同步顺利完成。The second stage of Nanjing Deji Plaza is a large-scale building of sixty-two layers main tower building layers with five layers basement.The podium part of this building is constructed by reverse construction method where diaphragm wall is used as exterior protected construction,beam and slab structure serve as horizontal support.Earth excavation is a key step for the foundation and the underground horizontal structure is constructed together with earth excavation.Based on demands of design,earth excavation with layered,zoned,symmetrical and streamlined are introduced.The results show that the excavation and basement construction are successful.
