Nowadays, safety evaluation before bridge opening is increasingly emphasized in our country.Bridge inspection is important to guarantee the safe operation of the bridge.In order to comprehensively assess the bearing capability and working conditions of Nanxi bridge of Lechangxia water complex, through static loading test and dynamic loading test,we measured the deformability and mechanical properties of bridge beams with different span-ratios and different forms.Basing on the results of dynamic/static loading test as well as the analysis of structure calculation, we conclude that the bearing capability and working /technological state of the bridge are excellent.The knowledge gained from this study can be used as an evaluation reference in the quality evaluation of the same type of projects.
