Steel truss web combined beam cable-stayed bridge
The invention discloses a steel truss web combined beam cable-stayed bridge, which comprises stiffening beams, stay cables, a cable bent tower, connecting piers and auxiliary piers, wherein the stiffening beam is mainly composed of two side spans and a midspan; each side span is mainly composed of a steel truss web double-combination beam; the midspan is mainly composed of steel truss web single-combination beams, each steel truss web double-combination beam comprises a double-combination-beam upper-layer concrete plate, a double-combination-beam lower-layer concrete plate and a double-combination-beam steel web member, and each steel truss web single-combination beam comprises a single-combination-beam upper-layer concrete plate, a single-combination-beam lower-layer steel chord member and a single-combination-beam steel web member; the steel truss web double-combination beam and the steel truss web single-combination beam are connected with the cable bent tower through stay cables; each steel truss web double-combination beam is supported through the connecting pier and the auxiliary pier; the connecting piers are arranged at the ends of the stiffening beams; and the auxiliary piers are located between the connecting piers and the cable bent tower. The steel truss web combined beam cable-stayed bridge is clear in stress, high in rigidity and high in integrity, the material performance of steel and concrete is fully utilized, the maintenance workload is small, the economical efficiency is good, and structural stress and engineering design are optimized.
本发明公开了一种钢桁腹结合梁斜拉桥，包括加劲梁、斜拉索、索塔、连接墩和辅助墩，加劲梁主要由两个边跨和中跨构成，每个边跨主要由钢桁腹双结合梁构成，中跨主要由钢桁腹单结合梁构成，钢桁腹双结合梁包括双结合梁上层混凝土板、双结合梁下层混凝土板和双结合梁钢腹杆，钢桁腹单结合梁包括单结合梁上层混凝土板、单结合梁下层钢弦杆和单结合梁钢腹杆；钢桁腹双结合梁、钢桁腹单结合梁均通过斜拉索与索塔相连；每个钢桁腹双结合梁均通过连接墩和辅助墩支撑，并且连接墩设置于加劲梁的端部，辅助墩位于连接墩和索塔之间。本发明受力明确、刚度大、整体性强、充分利用钢材和混凝土的材料性能、维养工作量小、经济性好，优化结构受力和工程设计。
