市政跨河桥梁与地铁地下车站合建的设计研究

随着城市建设用地日趋紧张，规划市政桥梁与地铁线路（车站）空间叠加利用的情况越来越多，因此市政桥梁与地铁线路（车站）合建的设计研究也越来越重要。本文通过某市政跨河桥梁与地铁地下车站合建实际工程设计案例，对该类合建结构方案选择的影响因素、总体设计及细部设计进行探讨研究，结合该合建结构成功的建设运营情况，总结出市政跨河桥梁与地铁地下车站合建结构的设计经验，以期为今后类似工程提供有益的设计思路和经验借鉴。

Design and Research on Co-construction of Municipal Crossing-river Bridge and Subway Underground Station

With the increasing shortage of urban construction land, there are more and more cases of planning the overlapping utilization of municipal bridge and subway line (station). Therefore, the design and research on the co-construction of municipal bridge and subway line (station) are becoming increasingly important. The influencing factors in selection, overall design and detailed design of the co-construction structure scheme are discussed and studied through a design case of a co-construction project of municipal crossing-river bridge and subway underground station. Based on the successful construction and operation of the co-construction structure, the design experience in the co-construction structure of the municipal crossing-river bridge and subway underground station is summarized in order to provide the useful design ideas and experience references for the similar projects in the future.
