Suspension bridge tower and construction method thereof
The invention discloses a suspension bridge tower and a construction method thereof, and belongs to the field of suspension bridge structures, the suspension bridge tower comprises a bearing platform and a lower cross beam, the lower cross beam is a steel structure-reinforced concrete combined cross beam, cross beam inclined struts are connected between the lower cross beam and the bearing platform, and the cross beam inclined struts are symmetrically arranged along the center line of a bridge; the construction method comprises a step that before the lower cross beam is closed, opposite jacking force is applied to a closing opening of the lower cross beam; the steel-concrete combined cross beam with the cross beam inclined struts is adopted, the stress problem of the lower cross beam is effectively solved, the span of the lower cross beam can be reduced through the cross beam inclined struts, so that the bending moment of the lower cross beam is reduced, and compared with a traditional reinforced concrete lower cross beam, the steel-concrete combined lower cross beam is higher in bending resistance and shear resistance. Therefore, the stress of the lower cross beam can be improved by adopting the structural form of the invention.
本发明公开了一种悬索桥桥塔及其施工方法，属于悬索桥桥梁结构领域，所述悬索桥桥塔包括承台和下横梁，所述下横梁为钢结构‑钢筋混凝土组合横梁，所述下横梁与所述承台之间连接有横梁斜撑，所述横梁斜撑沿桥梁中心线对称设置；本发明的施工方法在于下横梁合龙前，对所述下横梁的合龙口施加对顶力；本发明采用了加横梁斜撑的钢‑混凝土组合横梁，有效地解决了下横梁的受力问题，横梁斜撑可以减小下横梁跨度，从而减小下横梁弯矩，而钢‑混凝土组合下横梁比传统的钢筋混凝土下横梁抗弯及抗剪能力强，故而采用本发明的结构形式能够改善下横梁的受力。
