Design method of subway station-viaduct synchronous and same-position separation combined construction structure system
The invention discloses a design method of a subway station-viaduct synchronous and same-position separation combined building structure system. The building structure system comprises an open cut foundation pit, a supporting structure of the open cut foundation pit, a subway station structure and a viaduct structure. The vertical columns of the subway station structure and the pile foundations of the viaduct structure are vertically coaxial, and the longitudinal distance is consistent. The viaduct steel tube concrete pile foundation and the subway station structure are vertically separated, vertical stress and deformation of the two structures are mutually independent, and structural design analysis is simple; the subway station stand column adopts the mode that the prefabricated hollow column sections are vertically overlapped, has good vertical bearing capacity and horizontal interlayer deformation capacity, and can improve the overall anti-seismic performance of a subway station structure. Under the action of a horizontal earthquake, the viaduct steel pipe concrete pile foundation and the subway station laminated prefabricated hollow column section are coordinated in deformation and complementary in advantages. The structure system is small in occupied area, few in pipeline relocation and modification, low in construction cost and small in influence on urban landscape, and has good economic benefits and social values.
本发明公开了一种地铁车站‑高架桥同期同位分离合建结构体系的设计方法，建筑结构体系包括明挖基坑及其支护结构、地铁车站结构以及高架桥结构。地铁车站结构的立柱与高架桥结构的桩基竖向同轴，且纵向间距一致。高架桥钢管混凝土桩基与地铁车站结构竖向分离，两个结构的竖向受力和变形相互独立，结构设计分析简单；地铁车站立柱采用预制空心柱段竖向叠加的方式，具有较好的竖向承载能力和水平层间变形能力，能够提高地铁车站结构的整体抗震性能。水平地震作用下，高架桥钢管混凝土桩基与地铁车站叠层预制空心柱段变形协调，优势互补。本发明结构体系占地小，管线迁改少，工程造价低，对城市景观影响小，具有较好的经济效益和社会价值。
