【 摘 要 】

In order to inspect mechanical behavior analysis of long-span steel truss arch bridge, the spatial finite element model was established to analyze the mechanical behavior of the structure under static load and mobile load. Static load test of three span continuous steel truss arch bridge was carried out. The strains, deflection and the tension of the slings were measured. Comparison of testing data with the theoretical values obtained from finite element analysis was carried out. The results showed that the strength and stiffness of the bridge met the design requirements, and the static load test results were basically consistent with the theoretical analysis, which verified the mechanical characteristics of the bridge.
