摘要
文章在分析回顾多塔悬索桥结构特性研究进展的基础上,初步总结了多塔悬索桥力学行为规律;基于主缆垂跨比、中塔纵向刚度等参数对结构静、动力性能的影响趋势分析,建立了大跨径多塔悬索桥结构参数选取决策分析模型,使用层次分析法(AHP)对各设计参数进行了重要性排序,得出中塔纵向刚度、主缆垂跨比及加劲梁支承形式是影响结构整体性能的主要因素,指出了设计阶段参数选择的次序。
Based on the review on the structural property studies of multi-tower suspension bridge,a summary of its mechanical behavior is given.Considering the influence trend of such parameters as sag-span ratio of main cable,bending rigidity coefficient of center tower on static and dynamic properties,a decision model of structural parameter selection is established and the importance order is given by the Analytic Hierarchy Process（AHP）.The conclusion is made that bending rigidity coefficient of center tower,sag-span ratio of main cable and connection type of stiffened girder are the main factors influencing structural properties,and the parameter selection sequence in the design is given.
