| Abstract: | In this paper,the construction process of prestressed concrete continuous box-girder bridge with varying depth is simulated by FEM.The influence of dead load and temperature change on the displacement and stress of the bridge is explored and some meaningful conclusions are drawn for the construction control of continuous box-girder bridge. |
