The invention relates to a high-intensity earthquake area airport GTC high-speed rail elevated station bridge and a construction method thereof, and belongs to the technical field of rail transit bridges, the high-intensity earthquake area airport GTC high-speed rail elevated station bridge comprises a high-speed rail elevated station bridge composed of a main track bridge, an arrival-departure track bridge, a non-column metal canopy, a platform beam and a contact network, and the main track bridge and the arrival-departure track bridge are separated. The lower part of the main track bridge adopts a round-end pier, and the foundation adopts a pile group foundation; pi-shaped piers are adopted for arrival-departure line bridges, and pile group foundations are adopted for foundations; the column-free metal canopy, the arrival-departure line box girder and the platform girder are arranged on the arrival-departure line pi-shaped pier; the contact net is welded on a stand column of the column-free metal canopy; the anti-seismic performance is good, in the construction process, the construction sequence problem of the canopy foundation and the bridge is solved, and the construction period is shortened. Compared with a traditional bridge platform bridge, the functions are more complete and reasonable; compared with a traditional bridge building integrated platform, the engineering scale is reduced.
本发明涉及一种高烈度地震区机场GTC高铁高架车站桥梁及其施工方法,属于轨道交通桥梁技术领域,包括由正线桥梁、到发线桥梁、无柱金属雨棚、站台梁及接触网组成的高铁高架车站桥梁,正线桥梁与到发线桥梁采用分离式,正线桥梁下部采用圆端型桥墩,基础采用群桩基础;到发线桥梁采用π型墩,基础采用群桩基础;无柱金属雨棚、到发线箱梁及站台梁设置在到发线π型墩之上;接触网焊接于无柱金属雨棚的立柱上;本发明不仅抗震性能好,且在施工过程中,解决了雨棚基础与桥梁的施工次序问题,缩短了施工周期。本发明相比传统桥梁站台桥,功能更加完善、合理;相比传统桥建合一站台,减少了工程规模。
