深圳地铁一期工程会展中心站结构设计

Structural Design of Exhibition Center Station of Shenzhen Metro (Phase Ⅰ)

深圳地铁一期工程会展中心站是一号线和四号线的十字交叉换乘站,采用土钉墙及锚杆结合钢管内支撑人工挖孔桩的围护形式,概述了车站结构设计的主要特点,着重介绍人工挖孔桩与内衬墙重合计算的计算模式,以及十字交叉区下二层车道板的空间有限元计算。

Exhibition Center Station of Shenzhen Metro (Phase Ⅰ) is a cross-typed interchange station for Shenzhen Metro Line No. 1 and No. 4. It adopts a very complicated supporting structure formed by manually digging pile with steel tube strut and soil nail wall with anchor bolt. This paper introduces main characters of structural design, especially, the calculation mode of manually digging pile with lining wall and the finite element calculation of slab at the crossing.
