摘要
研究目的：地铁车站土建投资约占总投资的60％，合理控制车站土建投资是降低城市轨道交通工程造价的关键之一。目前双层岛式地下车站一般采用箱型框架结构，柱网主要有无柱、单柱、双柱等形式，并沿纵向设框架大梁，横向为大板结构。本文以武汉地铁为背景，通过分析不同站台宽度双层岛式地下车站不同柱网条件下土建指标，提出并研究地铁双层岛式地下车站受力与经济性较为合理的结构布置方案。研究结论：通过对不同的布置方式逐一研究对比，得出如下结论：（1）站台宽度为10-12m时采用单柱双跨形式，站台宽度为13-15m时采用双柱三跨形式，结构受力合理，造价较为节省；（2）站台宽度为13m时采用单柱双跨形式造价增幅较小，且车站功能显著提升，具备条件时可以使用；（3）相关研究成果可广泛应用于城市轨道交通地下车站的设计和施工。
Research purposes： The investment of subway station construction accounts for about 60% of the total investment. Accordingly, reasonably controlling the investment of station construction is one of the keys to reduce the cost of urban rail transit project. Now, the box frame structure with longitudinal frame beam and transverse large span slab is generally used in underground island platform subway station, and the column grid can be designed as no column, single column and double column form. This paper, taking Wuhan metro as the background, studies reasonable structural layout scheme in mechanical behavior and economy by analyzing the economic index of different platform width and different column grid of double decked island - platform underground station. Research conclusions：Through the comparison, the following conclusions are drawn： （1） The platform width of 10 - 12 m in the form of single column and double spans is reasonable in mechanical behavior and economy. Also, the platform width of 13 - 15 m with double column and three spans is reasonable. （2） When the platform width is 13 m, the form of single column and double spans is the most optimal in economy, and also the station function significantly increased. So, when the condition is allowed, this form is recommended. （3） The research resuhs can be widely used in the design and construction of urban rail transit underground station.
