| Abstract: | The article takes a 3-span 30-m double-curve arched bridge(Tushan Bridge)as an example to determine the reasonable load test scheme and to test based on the structural features and reinforcement characteristics of this bridge.The large-sized common finite element structural analysis program ANSYS is used to carry out the static and dynamic calculations of the bridge,and to analyze and compare with the test result so as to carry out the comprehensive evaluation of the reinforcement result and the bearing capacity of this double-curve arched bridge |
