Single-span integral seamless bridge structure adopting steel box composite beam and construction method
The invention discloses a single-span integral seamless bridge structure adopting a steel box composite beam and a construction method. The single-span integral seamless bridge structure comprises a steel box beam, a concrete bridge deck slab, a flexible pile foundation, a bridge abutment and an abutment back structure, and a top plate of the steel box beam is connected with the concrete bridge deck slab into a whole through a bridge deck slab connecting system; a steel box beam and bridge abutment connecting system extends into the bridge abutment and is integrally poured with the bridge abutment; one end of the abutment back structure is in pouring connection with the bridge abutment, and the other side of the abutment back structure is buried in soil. Besides the advantages of a traditional seamless bridge, the steel box composite beam is adopted, so that the structural dead weight is reduced, the bridge has better anti-seismic property, the applicable span of the bridge can be further increased, meanwhile, the structural height is reduced, and the clearance under the bridge is increased. The abutment connecting system is reasonable in stress, and the seamless connection betweena main beam and the abutment can be effectively guaranteed. In the aspect of construction, the steel box composite beam is high in erecting speed and high in bridge forming precision, existing traffic under the bridge is not affected, and the structure is particularly suitable for overpass bridges.
本发明公开了一种采用钢箱组合梁的单跨整体式无缝桥梁结构及施工方法，包括钢箱梁、混凝土桥面板、柔性桩基础、桥台和台后结构，钢箱梁的顶板通过桥面板连接系统与混凝土桥面板连接成整体，所述钢箱梁桥台连接系统伸入桥台内并与桥台浇筑为一体；所述台后结构一端与桥台浇筑连接，另一侧填埋于土中。除了具有传统无缝桥梁的优点，本发明采用钢箱组合梁既减轻了结构自重，从而使桥梁具有更好的抗震性能，可以使桥梁适用跨径进一步增大，同时又降低了结构高度，增加了桥下净空。桥台连接系统受力合理，能有效保证主梁与桥台的无缝连接。施工方面，钢箱组合梁架设速度快，成桥精度高，不影响桥下既有交通，特别适用于跨线桥。
