Dispersed self-anchored central main cable steel truss girder cable-stayed-suspension cable cooperative system bridge and method
The invention relates to a decentralized self-anchored central main cable steel truss girder cable-stayed-suspended cable cooperative system bridge and method, the decentralized self-anchored central main cable steel truss girder cable-stayed-suspended cable cooperative system bridge comprises a tower girder main body, the tower girder main body comprises at least two bridge towers which are arranged at intervals along the bridge direction, a steel truss girder is supported on cross beams of the two bridge towers, and the steel truss girder comprises a main span girder section located on a main span and a side span girder section located on a side span; the stay cable system comprises a double-cable-plane stay cable, the upper end of the double-cable-plane stay cable is anchored to the bridge tower, and the lower end of the double-cable-plane stay cable is anchored to the two sides of the steel truss girder; the suspension cable system comprises a central main cable supported at the top of the bridge tower and a plurality of slings suspended at the central position of the main span beam section, and the central main cable is gradually separated from the tower top to the side span direction and then is dispersedly anchored at the central position of the side span beam section. The problems that a conventional cooperative system bridge adopts two different construction methods and devices, so that the construction cost is relatively high, and the cable-stayed area and the cable-suspended area are difficult to close are solved.
本申请涉及分散自锚式中央主缆钢桁梁斜拉‑悬索协作体系桥及方法，包括：塔梁主体，该塔梁主体包括沿顺桥向至少两座间隔设置的桥塔，两座桥塔的横梁上支承有钢桁主梁，钢桁主梁包括位于主跨的主跨梁段，以及位于边跨的边跨梁段；斜拉索系，该斜拉索系包括双索面斜拉索，双索面斜拉索的上端锚固于桥塔，双索面斜拉索的下端锚固于钢桁主梁的两侧；悬吊索系，该悬吊索系包括支承在桥塔顶部的中央主缆和悬吊主跨梁段中央位置的多根吊索，中央主缆由塔顶向边跨方向逐渐分开后分散锚固于边跨梁段的中央位置。本申请避免了常规协作体系桥采用两套不同施工方法和设备导致施工成本相对较高、斜拉区和悬索区难以合龙等问题。
