| Abstract: | The support is the bearing structure in the construction process of cast-in-place beam. Its strength, rigidity and stability directly affect the quality and safety of the structure. Taking the cast-in-place construction of U-shaped continuous girder in Hanji Railway crossing 316 National Highway as an example, the article describes the design of bowl-coupler and section steel support, determines the load distribution, sets up the stress analysis model and verifies the scheme feasibility able to be referred for the construction of the similar projects. |
