The swivel T rigid bridge is a common bridge structure widely applied under special conditions such as crossing railways,highways,and complex terrain.Before the swivel of the bridge,the complete bridge quality and the construction period are two crucial factors.Based on a practical overpass engineering of Mingcun-Dongjiakou Highway Engineering over Jiaoxin Railway,this paper determined the T-rigid cast-in-place support system according to filed conditions,which combines beam-column bracket and ring-lock bracket,and introduced the design scheme and key construction technologies.The finite element analysis software MIDAS Civil was used to establish the calculation model of the temporary bracket to analyze the strength,stiffness,and stability of materials in each part of the bracket.The results showed that the cast-in-place bracket was feasible.
