Arch continuous beam bridge,as a new type of bridge formed by combining arch bridge and continuous beam bridge,is designed to meet the requirements of water construction of arch continuous beam bridge and the accuracy requirements of structural curve box beam con-struction support.The combination of steel pipe Bailey support and buckle type full hall support is used to form a concrete cast-in-place construction composite support.According to the design plan,a simplified model of the support is established using finite element program,and the stress calculation is carried out through finite element method.The results show that the con-struction support structure is safe and reliable,and the cast-in-place concrete construction combi-nation support meets the requirements;and provide a detailed introduction to the construction process and preloading method of the cast-in-place concrete construction combination support,which can serve as a reference for similar engineering construction plans.
