Subway station and municipal bridge separation type combined construction structure and construction method
The invention discloses a metro station and municipal bridge separation type combined construction structure and a construction method. The metro station and municipal bridge separation type combined construction structure comprises a main body structure of a station, and the main body structure is a closed frame structure; a pile foundation bearing platform and a pile foundation connected with the pile foundation bearing platform are arranged below the main body structure, a mattress layer is arranged above the main body structure, and a bridge bearing platform is arranged on the main body structure through the mattress layer. According to the station structure at the viaduct bearing platform, the cross beams and the embedded columns are arranged to form a closed frame structure, the structural rigidity is enhanced, and station component deformation and cracking caused by viaduct loads can be effectively reduced. Meanwhile, the viaduct is separated from the subway structure, the mattress layer is arranged between the viaduct and the subway structure, the structure stress is clear, the problem that the overground structure and the underground structure are not uniform in design theory and specification is solved, and the viaduct has the advantages of being small in influence on the surrounding environment, simple in construction procedure and better in anti-seismic performance of a high-intensity area.
本发明公开了一种地铁车站与市政桥梁分离式合建结构及施工方法，包括车站的主体结构，所述主体结构为闭合框架结构；所述主体结构下方设置桩基承台和与所述桩基承台连接的桩基础，所述主体结构上方设置褥垫层，桥梁承台通过所述褥垫层设置在所述主体结构上。本发明中高架桥承台处车站结构通过设置横梁及暗柱形成闭合框架结构，增强结构刚度，能有效降低高架桥荷载引起的车站构件变形及开裂。同时高架桥与地铁结构脱离，中间设置褥垫层，结构受力明确，解决了地上结构与地下结构设计理论及规范不统一的问题，且具有对周边环境影响小、施工工序简单、高烈度区抗震性能更优的特点。
