摘要

摘要: 以深圳太平金融大厦深基坑工程为背景分析了圆环内撑、格构式对撑及角撑+对撑的支护结构特点，最终选用了桩+角撑+对撑+南侧挖通放坡+大间距立柱的桩撑支护结构，节省了工程造价和工期。地下室换撑采用了不常用的换撑梁换撑，利于地下室外墙防水施工和预留空间回填，也节约了工期。实施和监测结果表明，整个施工过程达到了安全可控的目标，较好的保护了工程环境，为以后的类似工程设计提供了参考。

Abstract: Different retaining structures are analyzed for the deep excavation of Taiping Financial Center in Shenzhen, that is, circular bracing, lattice bracing and opposite bracing + gusset bracing. Finally the bracing structure of pile + gusset + support + south slope + large spacing vertical pile is selected. The project cost and construction time are saved. The beam of bracing replacement is adopted in the bracing replacement. It is in favor of waterproof construction of basement wall and filling of reserve space, and the construction time is also saved. The monitoring results indicate that the procedure of construction is safe and the deformation of the surrounding facilities is under control. These solutions may provide good reference for the design of future similar projects.
