市区某地铁站地下空间的结构设计

The Structural Design of Underground Space of a Subway Station in the City

城市地铁建设的快速发展带动了地下空间资源的大规模开发,结合地铁1号线建设开发的南街地下空间位于福州市中心主干道下方,是集商业与交通、平时与战时为一体的大型地下空间。为确保地铁建设工期以及减少施工对社会交通的影响,设计了3个阶段的交通疏解方案并分3期施工。为保证地下结构设计的安全性、经济性与耐久性,利用有限元程序进行多工况分析。为确保叠合墙成墙质量,探讨了叠合墙设计与施工的关键问题。

The rapid development of urban subway construction led to the large-scale development of underground space resource. South street underground space which combines with the construction of subway line No.1 located at the center of Fuzhou city main road, is a large underground space, which serves as business and transportation, peacetime and wartime. In order to ensure the subway construction period and reduce the impact of construction on the social traffic, traffic relief program designed as three-stage, stage construction of underground space was taken. In order to guarantee the safety, economy and durability of underground structure, multi-condition finite element analysis was used for more analysis and comparison of different conditions. In order to ensure the quality of the composite wall, the key problems of design and construction of composite wall are discussed.
