摘　　要：结合工程实例,研究了索拱结构选型和有限元分析的方法,分析了支座刚度、高跨比、拱身截面、索截面等各项参数对其受力性能的影响。研究了预应力索拱结构平面外和平面内的稳定性能。结合工程实例介绍了索拱结构的工程应用,并给出了设计建议。The characteristics of prestressed cable-arc structures are introduced. The influences of different parameters such as the supporting stiffness, ratio of height to span, arc section and cable section on the performance of cable-arc are analyzed. The buckling performance of prestressed cable-arc structures are studied by elastoplastic method. The application of prestressed cable-arc structures is listed, and advices are proposed for design.
