地铁站与高架桥同期同位分离式合建方案设计研究

Design of the Metro Station and Viaduct Assembly with Simultaneous Separation Construction

为缓解合肥市日益紧迫的交通压力,合肥马鞍山路高架桥与地铁1号线需同位并行、同步建设。为解决该问题,设计采用了一种新型的站桥合一结构——"地铁站、高架桥同位分离式组合体结构",即地铁车站与高架桥同期开工,结构体在车站顶板与桥梁墩柱扩大基础之间采用防水层进行分离。计算分析表明,该结构形式安全可靠。目前,市政高架桥已经通车运营5 a,地铁车站已经通车运营1 a,取得了巨大的社会效益和经济效益。

In order to alleviate the increasing traffic pressure in Hefei City,the viaduct on Ma′anshan Road.and Hefei metro Line 1 need to be built simultaneously in the same site.To solve this problem,a new station and bridge assembly design is adopted,it is a structure with simultaneous but separated construction,namely the subway station and the viaduct will be constructed at the same time,but the station roof will be separated by a waterproof layer from the enlarged foundation of pier columns.Calculation and analysis show that the structure is safe and reliable.At present,the viaduct and metro station have been opened to traffic for 5 years and 1 year respectively,great social and economic benefits have been achieved.
