| 摘 要： | 利用钢管砼的本构关系,分析钢管初始应力对钢管砼拱桥稳定承载力的影响程度.钢管初始应力的存在降低了钢管砼拱桥稳定承载能力,不同荷载加载方式,钢管初始应力对钢管砼拱桥的稳定承载力影响程度不同.这为今后深入研究大跨度钢管砼拱桥钢管初始应力问题提供了参考.

| Abstract: | In terms of constitutive relation of existed initial stress concreted-filled steel tubular,author analyses the influence of initial stress in concrete-filled steel tubular arch bridges.The results show initial stress reduces stability and bearing capacity of concrete-filled steel tubular arch bridge;the influence of initial is not equal to different load conditions.These conclusions offer reference for thorough study of the initial stress in large span concrete-filled steel tubular arch bridges in future. |
