Abstract: In view of the present bridge suddenly destroyed in man-made and natural disasters,causing traffic disruption, to meet the need to set up emergency bridge quickly when sudden traffic blowout ,at the same time after the completion of the relief without disrupting traffic, a small amount of work is done by the conversion of Long-term bridge, which is the general idea of an emergency bridge transfer to Long-term bridge. This paper put forward two kinds solution of an emergency bridge transfer to Long-term bridge:1) emergency bridge transfer to Long-term bridge base on the Bailey beam;2)emergency bridge transfer to Long-term bridge base on the steel-concrete composite bridge. And these two kind of schemes in the overall structure of the emergency stages and long-term stages are analyzed by finite element analysis, and introduces the construction process of two schemes.
