摘　　要：高性能钢桥的建设已经成为当前桥梁创新的重要方向之一。介绍陕西省眉县霸王河交通桥的结构优势、设计要点、施工方法及安全监控,利用有限元分析软件MIDAS/CIVIL进行结构整体分析和稳定计算,并结合陕西省眉县干沟河交通桥施工监控,研究高性能钢管混凝土拱桥受力特性。结果表明,结构设计安全可靠,各项指标满足现行规范要求。500 MPa级高性能钢是一种性能优越的桥梁用钢,在中国桥梁工程建设中拥有广阔的推广和应用前景。Nowadays, high performance steel bridge becomes one of the important innovation directions of bridge. This paper introduced the structural advantages design parameters, methods and the key points of construction and monitoring of Shaanxi Meixian Bawang Traffic Bridge. Finite element analysis software MIDAS/CIVIL was used to analyze integral structural analysis and stability calculation. Combined with the construction monitoring of Shaanxi Meixian Gangou Traffic Bridge, the mechanical characteristics of high performance concrete-filled steel tubular arch bridge was explored. The results showed that the indexes can meet the corresponding requirements of specifications. Therefore, 500 MPa high performance steel has great advantages in social benefits and fabrication, and has a broad prospect of application in China.
