AbstractBased on same cross-section of continuous girder bridge with variable spandifferent span models with the ratio of sidespan and midspan as parameters were establishedand the impact coefficient was calculated. According to the calculation results of the parameters for this kind of bridgethe fitting analysis were carried out. It has a certain reference function to the concrete calculation of the impact factor of the conventional continuous beam bridge in the future.
