Truss hybrid beam cable-stayed bridge
The embodiment of the invention provides a truss hybrid beam cable-stayed bridge. The truss hybrid beam cable-stayed bridge comprises cable bent towers, stay cables, a mid-span truss beam, side-span truss beams and steel-concrete combined sections. The mid-span truss girder comprises a mid-span steel truss and a lower-layer steel bridge deck structure connected with the mid-span steel truss; the mid-span truss girder is connected with the cable bent tower through a plurality of stay cables; the side-span truss girder comprises a side-span steel truss and a lower-layer concrete structure; the side-span steel truss comprises two side-span main trusses, each side-span main truss comprises a side-span upper chord and a plurality of side-span web members, and the bottom ends of the side-span web members are connected with the lower-layer concrete structure; each of the two opposite ends of the mid-span truss girders in the longitudinal bridge direction is provided with a side-span truss girder, and each mid-span truss girder is connected with the cable bent tower through a plurality of stay cables; and the lower-layer steel bridge deck structure is connected with the lower-layer concrete structure of each side span truss girder through a steel-concrete combined section. The truss hybrid beam cable-stayed bridge disclosed by the embodiment of the invention is relatively high in economical efficiency while ensuring the driving comfort.
本申请实施例提供了一种桁架混合梁斜拉桥，包括索塔、斜拉索、中跨桁架梁、边跨桁架梁和钢混结合段；中跨桁架梁包括中跨钢桁架和与中跨钢桁架连接的下层钢桥面结构；中跨桁架梁与索塔之间通过多根斜拉索连接；边跨桁架梁包括边跨钢桁架和下层混凝土结构；边跨钢桁架包括两片边跨主桁，边跨主桁包括边跨上弦杆和多根边跨腹杆，边跨腹杆的底端与下层混凝土结构连接；中跨桁架梁沿纵桥向的相对两端的每一端分别设置有一个边跨桁架梁，每个中跨桁架梁与索塔之间分别通过多根斜拉索连接；下层钢桥面结构与每个边跨桁架梁的下层混凝土结构之间分别通过一个钢混结合段连接。本申请实施例的桁架混合梁斜拉桥在保证行车舒适性的同时，经济性也相对较高。
