Underground station of large-span open-web rigid frame beam type composite structure
The invention discloses an underground station of a large-span open-web rigid frame beam type composite structure. The underground station comprises a side wall tightly attached to an enclosure structure, and a top plate, a middle plate and a bottom plate which are arranged on the top, the middle and the bottom of the side wall respectively. The top plate is of a large-span open-web rigid frame beam type combined structure and is composed of a cast-in-place slab and a prefabricated slab, the prefabricated slab is in an arc shape, and supporting points are arranged in the middle and on the two sides of the prefabricated slab to serve as a supporting structure of the cast-in-place slab; two side parts of the top plate are fixedly connected with the side walls; and the hollow cavities on the two sides of the top plate form a pipeline channel. The underground station has the advantages that the top of the underground station is of a large-span open-web rigid frame beam combined structure, the dead load of upper filling soil is reduced, the open-web structure of the top plate and the side walls jointly form a consolidated box body structure, the end rigidity is increased, the mid-span bending moment is greatly reduced, the structure thickness can be reduced, and the overall stress system is more reasonable; the upper portion adopts a prefabricated and cast-in-place combined structure, construction quality and apparent landscape are guaranteed, construction supports are reduced, and the waterproof function is guaranteed.
本发明公开了一种大跨空腹刚构梁式组合结构的地下车站，包括紧贴围护结构设置的侧墙以及分设于侧墙顶、中、底部的顶板、中板和底板；顶板为大跨空腹刚构梁式组合结构，由现浇板和预制板组成，预制板呈弧形，在预制板的中间和两侧设置支撑点以作为现浇板的支撑结构；顶板的两侧部与侧墙固定连接；顶板的两侧空腹式空腔构成管线通道。本发明的优点是：地下车站的顶部采用大跨空腹刚构梁组合结构形式，减小了上部填土自重荷载，且顶板空腹式结构与侧墙共同形成固结箱体结构，增大了端部刚度，大大减少跨中弯矩，可减少结构厚度，整体受力体系更加合理；上部采用预制和现浇组合结构，保证了施工质量和表观景观，减少施工支架，确保了防水功能。
