Box-type combined beam of railway long-span cable-stayed bridge
The invention provides a box-type combined beam of a railway long-span cable-stayed bridge. The box-type combined beam of the railway long-span cable-stayed bridge comprises concrete bridge deck slabsarranged at the top, an arc-shaped bottom plate arranged at the bottom, side main beams arranged at two sides in the transverse direction of a bridge and a plurality of diaphragm plates connected between the two side main beams, wherein the diaphragm plates are arranged at intervals along the bridge, and the arc center of the arc-shaped bottom plate is positioned above the arc-shaped bottom plate. The combined beam is clear in stress, large in transverse rigidity and high in integrity, the streamline section has good wind resistance, the main beams are higher in middle and lower in two sidesto fit with the transverse stress characteristics of a wide main beam, the material properties of steel and concrete can be fully utilized, the economic efficiency is good, the concrete bridge deck slabs are convenient to construct, the maintenance workload is small, and the composite beam can be widely applied to four-line or even six-line railway long-span cable-stayed bridges, and particularlyhas more advantages when being applied to ballastless track structures.
本发明提供了一种铁路大跨斜拉桥箱型组合梁，包括设置在顶部的混凝土桥面板，设置在底部的弧形底板，设置在横桥向两侧的边主梁，以及连接在两边主梁之间的横隔板；所述横隔板有若干个，沿顺桥向间隔布置，所述弧形底板的弧心位于弧形底板上方。该组合梁受力明确，横向刚度大，整体性强，流线型截面具有良好抗风性能，主梁中间高两侧低契合宽主梁横向受力特性，能够充分利用钢材和混凝土的材料性能，经济性好，混凝土桥面板施工方便，维养工作量小，能广泛运用于四线甚至六线铁路大跨斜拉桥，尤其在应用于无砟轨道结构上更具优势。
