Support Design and Analysis of Cast - In Situ Prestressed Continuous Box Beam Bridge

Abstract:

Based on DaZhangCun Grand Bridge across HejingYuncheng Highway’s specific conditions of DatongXian Passenger Dedicated Railway Line, construction method of group support and five segments pouring was designed. Support resistance during concrete placing and tension was analyzed by the software MIDAS/CIVIL and the mechanical behaviors of the bowl-scaffold support was identified while considering the gravity and construction load. Then targeted strengthening supports had been taken to ensure security.
