Large-span double-layer highway-railway dual-purpose steel truss composite beam cable-stayed bridge and design method thereof
The invention relates to a large-span double-layer highway-railway dual-purpose steel truss composite beam cable-stayed bridge and a design method thereof, and the large-span double-layer highway-railway dual-purpose steel truss composite beam cable-stayed bridge comprises a main steel truss which is provided with an upper layer longitudinal and transverse beam and a lower layer longitudinal and The main span comprises an upper-layer UHPC plate on the upper-layer longitudinal and transverse beams, a steel bridge deck plate on the lower-layer longitudinal and transverse beams and a lower-layer UHPC plate; the upper-layer UHPC board and the upper-layer longitudinal and transverse beams are combined to form a main-span upper-layer bridge deck, and the lower-layer longitudinal and transverse beams, the lower-layer steel bridge deck and the lower-layer UHPC board are combined to form a main-span lower-layer bridge deck; the side spans are located on the two sides of the main span in the bridge length direction and comprise common concrete bridge deck slabs on the upper-layer longitudinal and transverse beams, steel bridge deck slabs on the lower-layer longitudinal and transverse beams and lower-layer UHPC plates; the common concrete bridge deck and the upper-layer longitudinal and transverse beams are combined to form a side-span upper-layer bridge deck, and the lower-layer longitudinal and transverse beams, the lower-layer steel bridge deck and the lower-layer UHPC plates are combined to form a side-span lower-layer bridge deck. By means of the scheme, the cable-stayed bridge designed in a large-span scene has good economical efficiency and stability.
本申请涉及一种大跨度双层公铁两用钢桁结合梁斜拉桥及其设计方法，其包括：钢主桁架，其上设有上层纵横梁和下层纵横梁；主跨，其包括在上层纵横梁上的上层UHPC板、在下层纵横梁上的钢桥面板以及下层UHPC板；上层UHPC板与上层纵横梁结合形成主跨上层桥面，下层纵横梁、下层钢桥面板以及下层UHPC板结合形成主跨下层桥面；边跨，其在桥长方向上处于主跨的两侧，包括在上层纵横梁上的普通混凝土桥面板、在下层纵横梁上的钢桥面板以及下层UHPC板；普通混凝土桥面板与上层纵横梁结合形成边跨上层桥面，下层纵横梁、下层钢桥面板以及下层UHPC板结合形成边跨下层桥面。通过上述方案实现在大跨度场景下所设计得到斜拉桥的具有较好的经济性和稳定性。
