Construction Methods And Construction Control Of Large Span Arch Auxiliary Girder Bridge

In recent years, arch auxiliary beam bridge with its elegant appearance andunique structural performance in our rapid development, because of its lighter weight,high strength, large carrying capacity, and resistance to deformation is very prominentadvantages can be integrated to meetthe materials used in bridge building savings,ease of installation, weight bearing capacity of many requirements, large span archbridge an ideal structure. Arch auxiliary beam bridge construction process, thechanges in the force structure is relatively large, and the Arch arch bridge in terms ofimportance, to meet the requirements in order to ensure the linear and the force of thefinal into a bridge in the construction process of the arch auxiliary beam bridgeconstruction monitoring.In this paper, Guangyuan Jialing two-Bridge as the background arch auxiliarybeam bridge a variety of issues related to the construction and control technology,including auxiliary beam bridge arch construction technology, computer simulation ofthe construction phase of the analysis, and the construction processstructural stability,structural deformation, stress, and other monitoring and control. The main contentsare as follows:(l) details auxiliary beam bridge arch construction techniques, and analysis of themain beam of the the Guangyuan Jialing lane Bridge, and the construction of the mainarch.(2) combined with the the Guangyuan Jialing lane Bridge construction process,the finite element software modeling carried out by the force of the wholeconstruction process simulation analysis. First simulation analysis of the state of thethe Guangyuan Jialing lane Bridge bridge come sectional and combined stress as wellas the construction process in the deformation, and after the construction of the actualoperation to verify the correctness of the value of pre-migraine; followed on theGuangyuan Jialing two-the super bridge construction stage Rib steel pipe andconcrete pipe stress analysis, to predict the location of the maximum stress, andprovide a theoretical basis for the bridge construction monitoring and theoreticalguidance; final on Guangyuan Jialing lane bridge construction phase stability analysisverify the state and the construction sequence of the design of the construction of thethe Guangyuan Jialing lane Bridge is reasonably practicable, and to meet therequirements of the actual construction.(3) For the Guangyuan Jialing double lane Bridge, a concrete analysis of the of Guangyuan Jialing lane Bridge construction monitoring content and monitoring theresults, the comparison of the measured value and the theoretical value can be seen inthe process of construction monitoringstress and linear to meet the designrequirements of the basic theoretical and actual values; elaborate construction errorscaused arch auxiliary beam bridge construction monitoring process, and the copingstrategies for these errors.
