Beijing 100088 China) Abstract:The second stage of Nanjing Deji Plaza is a large-scale building of sixty-wo 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 exeavation with layered zoned symmetrieal and streamlined are introduced.The results show that the excavation and basement construction are successful. Key words:foundation excavation:undermining method:reverse construction method:deep foundation excavation 1工程概述 的距离约17m.周边环境图1所示. 南京德基广场二期工程总建筑面和265126m2 生主塔楼和裙楼组成，主塔楼62居，总高度320m: N 裙楼地上8层，总高度59m 地下5层.基坑总面积 约16000m2 基悦周长约552m.主楼基底标高为 主楼区城 -2...
