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. 
