| Abstract: | The finite element calculating model of the Pushan Arch Bridge is established by using the finite element program MIDAS/Civil,and the stability of space of the Pushan Bridge from the construction phase to the final stage are analyzed.The calculating result shows that the minimum value of the safety factor of stability at the construction phase is 13.05,and the maximum value at the first phrase of the final stage is 12.37.The bridge＇s stability is good.The obtained results can be used to design or construct bridges of the same kind. |
