Bridge and tunnel co-construction structure and construction method thereof
The invention belongs to the technical field of municipal engineering, and provides a bridge and tunnel co-construction structure and a construction method thereof. The bridge and tunnel co-construction structure comprises a bridge girder, bridge piers, a frame type tunnel structure, bridge pile foundations and deformation coordination piles. The tunnel structure is located under the bridge girder, and the center lines of the tunnel structure and the bridge girder on the plane are aligned. The bridge pile foundations serve as the anti-floating piles of the tunnel structure, the closed frame type tunnel structure also increases the transverse rigidity of the bridge pier, and land is saved in space through a mode of an upper bridge and a lower tunnel, so the problem that land acquisition andremoval in cities are difficult is solved; and stress components of the bridge pile foundations and the tunnel structure are fully utilized in a structural system, so the total engineering investmentis reduced from multiple angles. Meanwhile, the construction method of the bridge and tunnel co-construction structure has less influence on the flood discharge function of riverway, and is high in feasibility and low in construction cost.
本发明属于市政工程技术领域，提供了一种桥隧共建结构及其施工方法，该桥隧共建结构包括桥梁主梁、桥墩、框架式的隧道结构、桥梁桩基以及变形协调桩。所述隧道结构位于所述桥梁主梁的正下方，两者在平面上的中心线对齐。本发明提供的桥梁桩基兼做隧道结构的抗浮桩，闭合的框架式隧道结构亦增加桥墩的横向刚度，通过“上桥下隧”的做法在空间上节约用地，解决了城市中征地拆迁难的问题，结构体系上则充分利用二者的受力构件，多角度降低了工程总投资。同时，本发明提供的桥隧共建结构施工方法，对河道泄洪功能影响较小，可行性高、工程造价低。
