| Abstract: | According to the trait of the Jili Yellow River, a continuous prestressed concrete box girder bridge, which was constructed in span by span method with slide shuttering, a FEM of the entire bridge was established using the FEA program ANSYS. In addition, the process and the method of FEM Establishmeng were also introduced in detail, as provides the foundation for the study of the law of effect on the structure under different loads such as the movement of shuttering, self gravity of bridge, prestressing, bearing displacement, the changes of environment and so on. |
