The paper carries out load test and data analysis of five-span PC continuous box girder bridge,establishes spatial beam model by apply-ing large-scale finite element program Midas,carries out simulation analysis for continuous box girder bridge,and compares actual measurement value to theoretical value of bridge deformation and section stress under 6 kinds of experimental working conditions. Results show that:actual measurement value of bridge deformation and section stress is in accordance with its theoretical value,furthermore,both the bridge structure strength and rigidity meet design demands.
