This paper introduce the calculational program of coping elevation for free plate girder curve bridge and resolve the handworked calculational defect, it will useful for improving work efficiency.
The handworked calculational way of coping elevation for free plate girder curve bridge in expressway have more repeated workload, slow footed and easy to make a mistake.
