基于装配式地下结构的地铁车站多专业一体化配套设计关键技术

Key Technologies of Integrated Design for Multi-Speciality of Metro Station with Prefabricated Underground Structure

为解决多专业综合一体化在大型单拱无柱空间中的应用问题,完善装配式车站建筑设计理念,依托我国首次应用预制装配式地下结构的5座长春地铁车站的建筑、管线综合、装修等多专业一体化设计经验,研究车站建筑平面及空间布局、管线敷设、室内景观、声光电效果等环境因素影响,得出结论如下:1)车站公共区长度控制在90 m左右,设备区采用模块化布局并设置设备区夹层。2)公共区管线结合装修按“露、隐、藏”原则布局;设备区管线安装采用全新综合支吊架技术。3)装配式车站采用“清水”装饰风格,凸显高大拱形空间。

In order to solve the application problems of multi-speciality integration design in metro station with largescale 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.
