| Abstract: | Combined the design of prestressed concrete continuous box girder cast bracket across Tianmu River of the Second Hengqin River Bridge as an example, the scheme comparison on support design of cast-in-place box beam of broad width on seashore soft geological is proceeded. By using MIDASVCIVIL finite element structural analysis software, the column of bailey support spatial truss model is established, boundary condition is set up, the construction load is added. So the high simulation model and analysis of structure is conducted. The design method and construction requirement of fastener-style steel pipe supporting frame and portal channel in cast-in-place box beam are proposed systematically. They can provide reference for design and construction of the same type of bridge cast bracket. |
