Abstract：Research purposes: Based on the observing the stress and deformation in the control section and typical position of continuous box girder bridge under different static loads，the actual stress distribution and deformation of the bridge are obtained and based on the testing the actual stress of the bridge，the actual load—beating capacity of the bridge can be assessed and determined for providing measured data for the acceptance check of completion works．
Research conclusions: Through the static and dynamic 10ad tests，the parameters about stress，deformation and frequency of the bridge are obtained．The tests results show the theoretical analysis and calculation method uses for the bridge are feasible，and with which the construction quality can be guaranteed and the rigidity and load bearing capacity of the bridge can meet the requirements of the design and relative standards．
