摘　　要：为解决复杂环境中特大钢管混凝土拱桥建设的施工难点,需要对斜拉扣挂法进行施工创新。本文针对特大钢管混凝土拱桥施工与BIM技术的应用展开研究,施工采用拱桥斜拉扣挂方法和BIM智能设计,大桥预应力控制效果理想。实测结果表明:大桥拱肋成拱后,拱肋线形及应力状态与一次落架状态吻合良好,抗拉强度高。BIM技术在桥梁复杂工程中的应用,减少了开挖的工程量,具有较高的经济性、环保性和适用性,可为相关桥梁建设提供技术参考。In order to solve the construction difficulties of extra-large concrete-filled steel tubular arch bridge in complex environment,it is necessary to innovate the construction of cable-stayed buckle hanging method.In this paper,the construction and BIM design technology of extra-large concrete-filled steel tubular arch bridge are studied.The cable-stayed buckle hanging method of arch bridge and BIM intelligent design are adopted in the construction,and the prestress control effect of the bridge is ideal.The measured results show that the line shape and stress state of the arch rib of the bridge are in good agreement with that of the first falling frame,and the tensile strength is high.The application of BIM technology in complex bridge engineering can reduce the amount of excavation work,and has high economy,environmental protection and applicability,which can provide technology and reference for related bridge construction.
