文章依托厦门市地铁1号线与2号线换乘车站（吕厝站），对城市桥梁下设置地铁车站的设计思路进行阐述。为了解决桥梁墩台集中力对地下车站结构不利影响的问题，采用数值模拟的方法对合建结构体系受力及抗震性能等方面进行分析，通过匹配孔跨、结构固结、加强地铁车站立柱、柱下设置桩基等措施，解决地铁车站在桥梁基础集中荷载下的结构受力、沉降控制、结构抗震等问题，以期能为今后类似车站的设计提供借鉴。

Lucuo station, a transfer station between Line 1 and Line 2 of Xiamen Metro, is designed to be located below an existing municipal bridge. In the paper, the design concept of the Metro station is described, the forcing condition and seismic performance of the bridgestation integrated structure are analyzed by means of numerical simulation. Countermeasrues, such as bridge span matching, structure reinforcement, station column strengthening and installing pile foundations below station columns, are taken to ensure that the structural forcing, settlement and seismic performance of the works can meet relevant requirements. 
