Model Test of Cantilever Casting Construction of Reinforced Concrete Arch Bridge

In order to demonstrate the feasibility of the construction technique of cantilever casting of a reinforced concrete arch bridge and the rationality of cable force adjustment and construction control,a model test of cantilever casting construction was made by taking the No.1 Baishagou bridge as project background.The displacement of model arch,the stress of control sections and the force of cables were tested.In addition,the test results were compared with calculated results based on the FEM(finite element method),showing reasonable agreement.The research results show that the model arch is safe during the construction,the construction technique of cantilever casting of reinforced concrete arch bridges is feasible,and the method of cable force optimization and adjustment is reasonable.
