摘　　要：施工方案的选取对桥梁的建设与运营安全是十分有必要进行考虑的,关系整个桥梁全寿命期的安全可靠性。本文以一座钢管混凝土拱桥为例,两种不同施工方案采用MIDAS/CIVIL空间有限元软件对其进行仿真分析计算,对钢管混凝土拱桥结构受力进行计算,将不同施工方案过程中的应力值进行对比,准确掌握拱桥结构的受力情况,为该桥的施工方案选取提供了可靠理论依据,为同类桥梁施工提供参考。The selection of the construction plan is very necessary for the construction and operation safety of the bridge,which directly relates to the safety and reliability of the entire bridge throughout its life.This paper takes a concrete-filled steel tube arch bridge in the western province as an example.Two different construction schemes are simulated and calculated by MIDAS/CIVIL space finite element software.The structural stress of the CFST arch bridge is calculated,and the stress during different construction schemes will be calculated.The values are compared to accurately grasp the stress of the arch bridge structure,which provides a reliable theoretical basis for the selection of the bridge construction scheme,and provides reference for similar bridge construction.
