Study on Construction Scheme of Superstructure of Long-span Continuous Rigid Frame Arch Bridge
In order to ensure the safety,economy and efficiency of the construction of long-span continuous rigid frame arch bridge,based on a subway(80+150+80)m long-span continuous rigid frame arch bridge,this paper studies the construction scheme of the superstructure of arch bridge under special and complex geographical location and environmental factors.Specifically,after comparing the construction environment,safety,technical feasibility,construction period and economy,the scheme of steel pipe pile+bailey beam support formwork+hanging basket cantilever pouring is selected to construct the superstructure of the bridge.The purpose of this study is to provide some reference for the construction of similar projects.
