Abstract:

This paper is aimed to verify the effects of reinforcement by tests before and after reinforcement of a two-way curved arch bridge with a clear span of 70m. Four 100kN and 180kN trucks are used for load tests of the bridge before and after reinforcement, and then the test values are compared with the calculated values. Tests before reinforcement has proved insufficient rigidity in some parts of the bridge, the design load grade is low, and the common fault in two-way curved arch bridges. The finite element numerical analysis tool ANSYS is used for finite element simulative analysis of the bridge, and the comparison of test values with calculated values shows the bridge can meet the existing design load grade after reinforcement. This paper has verified the feasibility and rationality of utilizing the physical unit of ANSYS for analysis of two-way curved arch bridges after reinforcement, and meanwhile, proved that the rigidity and design grade of bridges can be improved by reinforcement.
