摘要:
基于悬索桥线形分析理论和自锚式悬索桥的受力特点,采用对塔-梁有限元模型施加主缆内力的方法,近似考虑主缆、主梁和索塔共同工作的影响,以压缩刚度的形式对主缆空缆线形的计算进行修正; 以某大桥为工程背景,通过有限元实例分析阐述了此近似计算方法的运用。研究结果表明:该方法可作为一种考虑压缩修正的空缆线形计算方法,同时压缩变形对空缆架设的影响明显,在实际空缆架设中应予考虑。
Abstract:
Based on the analysis theory of the suspension bridge and the mechanical characteristics of self-anchored suspension bridge,the joint work of the main cable,beam and pylon were approximately considered by the method of executing internal forces to the pylon-beam finite element model of cables.Main cable curve was modified by calculation in the form of compression stiffness.The method was used in a practical bridge by finite element analysis.Results showed that the method could be used as one of the methods for free cable shaped calculation. Meanwhile, the compression deformation obviously affected the erection of the free cable,thus it should be considered in practical application.
