[摘要]深圳国际会展中心规划建设室内展厅总面积50万m2,整体建成后将是全球较大的会展中心。深圳国际会展中心由中央廊道、登录大厅、展厅等组成,设二层地下室。地下室为钢筋混凝土结构,地上为钢结构。主要介绍深圳国际会展中心基础设计、展厅地面软基处理、复杂超长地下室结构设计和地上钢结构方案的发展与演变,以及设计过程中的关键技术问题。经换填、堆载及管桩复合地基处理后,工后沉降不大于15cm,承载力不小于100kPa;超长地下室结构运行良好,无底板、外墙、楼板等构件出现因混凝土收缩和温度作用而开裂的现象;经过对钢结构方案进行多轮对比分析,展厅最终采用间距18m的空间三角桁架,登录大厅采用树状分叉柱+网格结构的结构方案,该方案经济合理,可为类似项目设计提供参考。

Abstract:Shenzhen International Convention and Exhibition Center plans to build an indoor exhibition hall with a total area of 500 000m2, which will be the larger convention and exhibition center in the world after its completion. Shenzhen International Convention and Exhibition Center is composed of central corridor, lobby and exhibition hall, etc, with two basement floors. The basement is reinforced concrete structure, and the structure on the ground is steel structure. The key technical issues in the design process of Shenzhen International Convention and Exhibition Center were mainly introduced as well as the foundation design, the soft foundation treatment of exhibition hall ground, the structural design of complex and super-long basement, the development and evolution of the above ground steel structure scheme. After replacement, surcharge and pile composite foundation treatment, the post construction settlement was not more than 15cm, and the bearing capacity was not less than 100kPa; the super-long basement structure operated well, and there were no phenomena of concrete shrinkage and temperature cracking in the bottom slab, outer wall and floor and other components; after multiple rounds of comparative analyses of the steel structure scheme, the spatial triangle truss with a spacing of 18m was finally used in the exhibition hall, and the lobby adopted the structural scheme of tree-shaped column and grid structure, the structural scheme is economic and reasonable, which could provide reference for the similar project designs.
