    摘要:

    分别介绍了抛物线法、分段悬链线法及节线法等 3 种计算理论。并用这 3 种方法分别计算了地锚式悬索 桥成桥坐标和空缆坐标。以分段悬链线法的计算结果作为验算标准,分析了基于 Midas/Civil2019 软件的节线法在 地锚式悬索桥线形分析过程中的优、缺点。研究结果表明:基于节线法的主缆线形计算是以节点平衡为依据进行 数值迭代的近似计算,其结果符合工程实际,对于设计和施工都具有借鉴意义。

    Abstract:

    Three calculation theories of the parabolic method, the segmented catenary method and the section line method are introduced. Three methods to calculate the bridge main cable coordinates and empty cable coordinates of the ground-anchored suspension bridge are used. The calculation result of segmented catenary method as the standards of verification, the advantages and disadvantages of the nodal method based on Midas/Civil 2019 software in the linear analysis process of the ground-anchored suspension bridge are described. The calculation of the main cable shape based on the nodal line method is the approximate calculation of numerical iteration is based on the node balance. The result is in line with the engineering practice and has certain practical significance for design and construction.
