Abstract

In view of the transverse deformation of super-wide steel box girders of cable-stayed bridges during the cantilever assembly，the construction characteristics of the two-way eight-lane super-wide steel box girder of Zhongshan Bridge over Shenzhen-Zhongshan Link were analyzed，and the main causes of the transverse deformation during the cantilever assembly of the super-wide steel box girder were investigated.According to the matching height difference adjustment technology in the cantilever assembly construction of the wide box girder in China and abroad，this paper innovatively proposed a matching process of straight beam locking + initial tension of hanging cables，which better solved the problem of poor transverse deformation during the cantilever assembly of the super-wide steel box girder of Zhongshan Bridge.
