Construction method of kilometer-level maglev rail transit suspension cable-arch combined bridge and bridge
The invention relates to the field of bridge construction, in particular to a construction method of a kilometer-level maglev rail transit suspension cable-arch combined bridge and the bridge, and the construction method comprises the following steps that construction of a main bridge tower is completed; a suspension cable main cable is erected on the main bridge tower, and the two ends of the suspension cable main cable are anchored to the concrete anchors; a plurality of suspension cable suspenders are installed on the suspension cable main cable; a main arch is erected below the suspension cable main cable, and the main arch is connected with the suspension cable main cable through a suspension cable suspender; a plurality of main arch suspenders are mounted on the main arch; a main beam is constructed below the main arch, and the main beam is connected with the main arch through a main arch suspender; and magnetic levitation track beams are installed on the main beams, and construction of the suspension cable-arch combined bridge is completed. The bridge comprises a main beam, a magnetic levitation track beam, a main arch and a main bridge tower forehead suspension cable main cable. The advantages that the arch bridge is high in rigidity and the suspension bridge is large in span are fully exerted, and the suspension bridge has the advantages of being high in overall rigidity, small in deformation, convenient to construct and the like and has wide application prospects in large-span maglev rail traffic engineering.
本申请涉及一种千米级磁浮轨道交通悬索‑拱组合桥梁的施工方法及桥梁，涉及桥梁施工领域，施工方法包括以下步骤：完成主桥塔的施工；在主桥塔上架设悬索主缆，并将悬索主缆的两端锚固于锚碇上；在悬索主缆上安装多个悬索吊杆；在悬索主缆的下方架设主拱，并通过悬索吊杆将主拱与悬索主缆连接；在主拱上安装多个主拱吊杆；在主拱的下方施工主梁，并通过主拱吊杆将主梁与主拱连接；在主梁上安装磁浮轨道梁，完成悬索‑拱组合桥梁的施工。桥梁包括主梁、磁浮轨道梁、主拱、主桥塔额悬索主缆。充分发挥了拱桥刚度大和悬索桥跨度大的各自优点，具有整体刚度大，变形小，施工方便等特点，在大跨度磁浮轨道交通工程中应用前景广阔。
