Viaduct large-span bearing platform structure crossing subway station and construction method of viaduct large-span bearing platform structure
The invention discloses a viaduct large-span bearing platform structure crossing a subway station and a construction method of the viaduct large-span bearing platform structure. The invention relates to a high-rise viaduct, which comprises a horizontally arranged large-span bearing platform beam, at least two pile foundations vertically arranged below the large-span bearing platform beam, an elevated pier column vertically arranged above the large-span bearing platform beam, a viaduct box beam horizontally arranged on the elevated pier column and a tension anchor cable part, and the pile foundations are uniformly distributed on the two sides of the large-span bearing platform beam; wherein the pile foundation on one side and the elevated pier column on the corresponding side are coaxially arranged, the elevated pier column and the pile foundation which are coaxial are connected through a rigid connecting piece, a plurality of sets of tensioning anchor cable components are arranged in the large-span bearing platform beam, and the multiple sets of tensioning anchor cable components are arranged in the longitudinal direction of the large-span bearing platform beam at intervals. The stretch-draw anchor cable component can improve the bending resistance of the large-span bearing platform beam. Loads borne in the transverse direction and the longitudinal direction are comprehensively considered, the stability and reliability of the large-span bearing platform structure are ensured, and the large-span bearing platform can be widely adopted when a bridge crosses an existing underground structure.
本发明公开了一种跨跃地铁车站的高架桥大跨度承台结构及其施工方法,其包括:水平设置的大跨度承台梁、至少两个竖向设置于大跨度承台梁下方的桩基、竖直设置于大跨度承台梁上方的高架墩柱、水平设置于高架墩柱上的高架桥箱梁以及张拉锚索部件,桩基均布于大跨度承台梁的两侧,其中一侧的桩基和对应侧的高架墩柱同轴设置,同轴的高架墩柱和桩基通过刚性连接件连接,大跨度承台梁内部设置有多组张拉锚索部件,多组张拉锚索部件沿大跨度承台梁的纵向方向间隔设置,张拉锚索部件能够提高大跨度承台梁的抗弯性能。本发明综合考虑横纵两个方向承受的载荷,确保大跨度承台结构的稳定性和可靠性,在桥梁跨越地下既有结构时可广泛采用。
