Construction method of bearing cable of cable crane for mounting main beam of suspension bridge
The invention discloses a cable crane bearing cable construction method for mounting a suspension bridge girder, which comprises the following steps of: anchoring a cable crane bearing cable on an upper cross beam of an adjacent cable tower, or anchoring one end of the cable crane bearing cable on an anchorage of a suspension bridge and anchoring the other end of the cable crane bearing cable on the upper cross beam of the adjacent cable tower to form cable crane single-span bearing cable arrangement; a simulation analysis model of the installation completion state of the suspension bridge main cable containing the cable crane bearing cable is established, and the construction safety is determined by analyzing and simulating the installation working condition and the stress of the working condition of the separated cable crane. Compared with the bearing cable arrangement of a traditional cable crane, the separated cable crane has the advantages that the non-working span bearing cable is omitted, the material loss of the bearing cable can be greatly reduced, the installation workload of the cable crane is reduced, and the construction cost is effectively saved; compared with a traditional cable crane, the vertical deformation is smaller under the working condition, the design rise-span ratio is optimized, the maximum cable force of the bearing cable is reduced, and the construction safety and reliability are improved.
本发明公开了一种悬索桥主梁安装用缆索吊机承重索施工方法，通过将缆索吊机承重索锚固于相邻索塔上横梁，或一端锚固于悬索桥锚碇，另一端锚固于临近索塔上横梁，形成缆索吊机单跨承重索布置，同时根据悬索桥设计施工图，建立包含缆索吊机承重索的悬索桥主缆安装完成状态的仿真分析模型，通过对分离式缆索吊机安装工况和工作工况的受力分析模拟，确定施工安全。本发明相较于传统缆索吊机承重索布置，分离式缆索吊机省去了非工作跨承重索，可大大降低承重索材料损耗，减小缆索吊机的安装作业量，有效节约施工成本；对比于传统缆索吊机的工作状况下竖向变形量更小，优化了设计矢跨比，减小承重索最大索力，提高施工安全可靠性。
