Description

technical field

[0001] The invention relates to a building construction technology, in particular to a bridge construction technology. Background technique

[0002] Cable-stayed bridge, also known as cable-stayed bridge, is a bridge in which the main girder is directly pulled on the bridge tower by many cables. structural system. It can be regarded as a multi-span elastically supported continuous beam with cables instead of piers. It can reduce the bending moment in the beam body, reduce the height of the building, reduce the weight of the structure, and save materials. A cable-stayed bridge consists of a cable tower, a main girder, and a cable-stayed bridge.

[0003] As a cable system, the cable-stayed bridge has a larger spanning capacity than the girder bridge, and is the most important type of long-span bridge. The cable-stayed bridge is a bridge deck suspended by many steel cables directly connected to the tower, and the cable-stayed bridge is composed of a cable to...
