Abstract

Abstract

In order to solve the situation that it is impossible to install temporary piers in the bridge span for special reasons such as flood season, a kind of walking jacking construction without temporary piers scheme for long-span steel-concrete composite bridges was studied, it has more advantages than the original design of trestle straight lifting, side sliding and other construction schemes. The scheme simulated hundreds of construction conditions and selected the optimal construction conditions for finite element analysis. Through the finite element analysis of the bearing capacity of steel bridge permanent pier, assembling platform, steel guide beam and steel beam itself, the results showed that the jacking construction without temporary piers scheme for steel-concrete composite bridges was safe, economical and reliable, and was worth popularizing.
- no temporary pier,
- steel-concrete composite box bridge,
- jacking,
- finite element
