Construction method of large-span wind-resistant suspension bridge
The invention provides a construction method of a large-span wind-resistant suspension bridge, which relates to the technical field of suspension bridge construction, and comprises the following steps: step 1, selecting a proper construction terrain, leveling the site, removing sundries, replacing and removing soft soil on the surface layer, and compacting; according to the method, the new main cable reinforcing cable is erected above the original suspension cable, the cable clamps are installed on the new main cable reinforcing cable and the original suspension cable, the new main cable reinforcing cable and the original suspension cable are bound through fixing of the cable clamps, then the effect of reinforcing the suspension cable is achieved, and meanwhile active balance weights are sequentially installed at the corresponding positions of suspenders of the suspension cable from the midspan to the side span; in addition, a prestressed expanded-end anti-sliding anchor pile can be additionally arranged on the anchor and combined with the original anchor into a whole to serve as an anchor of a newly-added suspension cable, so that the firmness of the suspension cable and the bridge body is improved, the suspension cable is not prone to shaking greatly under the influence of strong wind, and the shaking amplitude is reduced to a certain extent.
本发明提供一种大跨度抗风悬索桥施工方法，涉及悬索桥施工技术领域，包括以下步骤：步骤一：选择合适的施工地形，接着平整场地，清除杂物，换除地表层软土，夯压密实；本发明中，通过在原有悬索上方架设新的主缆加固索，在新的主缆加固索和原有悬索上安装索夹，通过索夹的固定将其相互绑定，进而起到加固悬索的作用，同时从跨中到边跨依次在悬索的吊杆对应位置安装主动配重，使应力达到预期成桥状态，还可以在锚碇上加设预应力扩头抗滑锚桩，并与原锚碇组合成为整体，作为新加悬索的锚固，从而提高了悬索以及桥体的牢固性，使悬索在大风影响下不易大幅度晃动，一定程度上减少了晃动的幅度。
