Super-long-span cable-stayed bridge and construction method
The invention relates to a super-long-span cable-stayed bridge and a construction method, and belongs to the technical field of cable-stayed bridges, the super-long-span cable-stayed bridge comprises a cable bent tower, a main beam and a stay cable, the main beam is erected on the cable bent tower, one end of the stay cable is fixedly arranged on the cable bent tower, the other end of the stay cable is fixedly arranged on the main beam, and air deflectors are arranged on the two sides of the main beam correspondingly; the number of the air guide plates on each of the two sides is two, the two air guide plates are arranged in a herringbone shape, the tip ends of the two air guide plates face the side away from the main beam, a plurality of air passing holes are formed in the plate faces of the air guide plates, and the air passing holes and the inner steel structure of the main beam are staggered. The method has the effect of reducing the shaking degree of the cable-stayed bridge.
本申请涉及一种超长跨度斜拉桥及施工方法，属于斜拉桥技术领域，包括索塔、主梁和斜拉索，所述主梁搭设在索塔上，所述斜拉索的一端固定设置在索塔上，另一端固定设置在主梁上，所述主梁的两个侧向均设置有导风板，两侧的所述导风板均为两块，两块所述导风板呈人字形排布，两块所述导风板的尖端朝向背离主梁侧，所述导风板的板面开设有多个过风孔，所述过风孔与主梁内部钢结构交错。本申请具有降低斜拉桥晃动程度的效果。
