Research On Key Technology Of Construction Of Rigidframed Arch With Steel-Box Continuous Beam Composite Bridge

Rigid frame arch steel box continuous beam composite bridge has beautiful appearance and novel structure,and it is increasingly used in modern bridge construction.However,the comparison and selection of the construction technology scheme of the bridge the design and construction of the temporary structure of the process,and the monitoring of various indicators of the process implementation are the issues that need to be solved before the engineers.This paper takes the(24 + 160 + 24)m steel tube concrete rigid frame tie bar arch steel box continuous beam composite bridge as the basis for the Foshan West Railway Station across the Guidan Road Bridge.This bridge is designed and implemented temporarily during the construction process.The key construction technology of the rear arch,construction monitoring measurement design and implementation were analyzed and researched.First research on the jacking method in the first beam process,summarize the advantages and disadvantages of different jacking methods based on case analysis,and summarize key technologies and process control measures by relying on engineering.Then study the factors that need to be considered for the selection of the bridge-type temporary project plan,the design calculation and verification of the key projects of the temporary engineering relying on the project are verified,and the rationality of the setting is verified.Finally analyze and plan the monitoring and measurement items in the construction process of the relying on the project,verify the implementation effect in the construction project,analyze the causes of deviations,and provide references for the construction of similar bridges.
