Abstract: Reinforced concrete continuous curved girder bridge is an important structure in highway traffic, due to the complex stress condition of the structure, the numerical simulation analysis before bridge design is particularly important. The finite element method is used to establish the calculation model of reinforced concrete continuous curved girder bridge, according to the load distribution characteristics during the construction and operation of the bridge, the calculation and analysis conditions of the bridge are designed, the most unfavourable position of bridge load is analysed. The results show that, the maximum longitudinal stress of bridge usually occurs at the middle section or support of continuous beam span, this is mainly the stress distribution law of continuous beam structure, the vertical displacement of the bridge shows regular fluctuations at the support and each middle span. The research results provide a reference for the design and construction of reinforced concrete continuous curved girder bridge.
