摘要
采用有限元软件MIDAS/Civil建立蒲山大桥空间有限元计算模型,分析了施工阶段及成桥后的空间稳定性。计算结果表明:蒲山大桥在施工阶段的稳定安全系数最小值为13.05,成桥后的第1阶稳定安全系数为12.37,桥梁稳定性较好,所得结果可为同类桥梁设计和施工提供参考。
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.
