Two-main-truss three-cable-plane main beam structure for cable bearing bridge
The invention relates to a two-main-truss three-cable-plane main beam structure for a cable bearing bridge, and belongs to the technical field of cable bearing bridges. The two-main-truss three-cable-plane main beam structure comprises an upper-layer bridge surface, a lower-layer bridge surface, a middle-layer bridge surface and a lower-layer bridge surface, the lower-layer bridge floor is provided with a two-line railway and a four-lane common road; the number of the main trusses is two, and the two main trusses are located on the two sides of the outer edges of the upper-layer bridge floor and the lower-layer bridge floor correspondingly and connected with the upper-layer bridge floor and the lower-layer bridge floor correspondingly; the transverse braces are respectively connected with the upper-layer bridge floor and the two main trusses; the three-cable surface comprises side cables connected to the two sides of the upper-layer bridge surface and a central cable connected to the middle of the upper-layer bridge surface. The main beam adopts a two-main-truss three-cable-plane arrangement, so that the cable force of a single stay cable is further reduced and the transverse stress of the main beam is improved on the premise of not increasing the width of a bridge floor and the construction cost.
本申请涉及一种缆索承重桥梁用两主桁三索面主梁结构，属于缆索承重桥梁技术领域，包括：上层桥面，所述上层桥面上具有双向六车道高速公路；下层桥面，所述下层桥面上具有两线铁路和四车道普通公路；主桁，其设置有两片，两片所述主桁分别位于所述上层桥面和所述下层桥面的外缘两侧，并分别与所述上层桥面和所述下层桥面连接；横联，其分别与所述上层桥面和两片所述主桁连接；三索面，其包括连接在所述上层桥面两侧的边索和连接在所述上层桥面中部的中央索。本申请主梁采用两主桁三索面布置，在不增加桥面宽度和工程造价的前提下，进一步减小单根斜拉索索力、改善主梁横向受力。
