Analysis on Construction Supervision of Steel-concrete Composite Continuous Box Girder
Through the construction supervision of 45 m+70 m+45 m variable cross-section steel-concrete composite continuous box girder of a super-large bridge the contents,methods and steps in the construction supervision of this kind of structural bridge are discussed.Midas Civil software is used to simulate and analyze the stress and deformation characteristics in the construction of steel-concrete composite continuous box girder.The stress and deformation states of each stage in the construction are obtained.Analyzed and compared with the practical construction situation,the reliability of calculation model and result has been verified,which shows that the adopted theoretical model can better reflect the practical working state of bridge structure.The construction supervision method has reached the expected effect.The related analysis results can be also used as the technical reference for the analysis on the construction supervision of the similar bridge structures.
