Box truss combined hybrid beam cable-stayed bridge
The invention discloses a box truss combined hybrid beam cable-stayed bridge, and belongs to the technical field of bridge engineering. The box truss combined hybrid beam cable-stayed bridge comprisesconcrete beams, a steel box-steel truss composite beam, connecting piers and cable bent towers, wherein the steel box-steel truss composite beam is arranged on the mid-span side of the cable-stayed bridge and comprises a steel box girder and a steel truss, the two concrete beams are arranged on the side span sides of the cable-stayed bridge respectively, the two ends of the steel box girder are connected with the ends of the corresponding concrete beams respectively, the concrete beams and the steel box girder are connected with the corresponding cable towers through a plurality of stay cables respectively, and thus the cable-stayed bridge structure stable in structure is obtained. The box truss combined hybrid beam cable-stayed bridge is simple in structure and convenient to construct, the steel consumption of the cable-stayed bridge is reduced while the overall rigidity of the cable-stayed bridge is improved, the traveling comfort of the cable-stayed bridge is guaranteed, the construction cost of the cable-stayed bridge is greatly saved, and the box truss combined hybrid beam cable-stayed bridge has good economic benefits and social benefits.
本发明公开了一种箱桁组合混合梁斜拉桥，属于桥梁工程技术领域，包括混凝土梁、钢箱‑钢桁组合梁、连接墩和索塔，其中，钢箱‑钢桁组合梁设置在斜拉桥的中跨侧，其包括钢箱梁和钢桁架，混凝土梁为分设于斜拉桥边跨侧的两根，且钢箱梁的两端分别与混凝土梁的端部连接，以及混凝土梁和钢箱梁分别通过多个斜拉索与对应索塔相连，从而得到结构稳定的斜拉桥结构。本发明的箱桁组合混合梁斜拉桥，其结构简单，施工便捷，提高斜拉桥整体刚度的同时，降低斜拉桥的用钢量，不仅保证了斜拉桥行车的舒适性，还大幅节约了斜拉桥的建设成本，具有较好的经济效益和社会效益。
