| Abstract: | The upper structure of the N37-N16 pier of the North Approach Bridge adopts steel-concrete composite beams,and some sections are designed with double-layer steel-concrete composite beams,which has a complicated structure.The steel beam is constructed by jacking method,and the precast concrete bridge deck is installed by bridge erecting machine and sliding method.This method is rare in China and even in the world,and it is difficult to construct.This study can provide reference for similar projects. |
