Abstract: In order to solve the application problems of multispeciality integration design in metro station with largescale single arch columnless space and improve the design concept of prefabricated station architecture, five Changchun metro stations, where prefabricated underground structures are applied for the first time in China, are studied. The experience of multispeciality integration referring to metro station architecture design, pipeline synthesis, and station decoration is introduced and the impact of environmental factors such as station building plane and space layout, pipeline laying, indoor landscape, acoustic and optical effects, are analyzed.  Combined with practical results, the exploration conclusions are as follows: (1) The public area of station is controlled at about 90 m in length, and the equipment area adopts modular layout and is provided with mezzanine. (2) Pipelines in public areas shall be arranged with the principle of "exposure, hinding and concealment" according to decoration requirement; for the pipeline installation in equipment area, new integrated support and hanger technology is adopted. (3) Prefabricated station adopts the "clear water" decoration style to highlight the tall arch space.
