Abstract
Based on the as-built load test of a large bridge, this paper introduces the procedure of the prestressed concrete continuous rigid frame bridge load test. Numerical analysis of the bridge was carried out by simulating and establishing a finite element model, and comparative analysis was carried out with the measured values. The results show that the calculated values were basically consistent with the measured values, which showed that the establishment method of the model was reasonable, and the mechanical performance of the bridge met the service requirements of the designed live load.
