三塔自锚式斜拉悬索协作体系桥吊索的优化设计

摘要

为了确定三塔自锚式斜拉悬索协作体系桥最优吊索方案，按照吊索张拉原则，提出了四套吊索张拉方案，并对该四套方案进行优化对比，提出最优方案；为以后同类桥梁设计及推广应用提供理论依据。%In order to determine the optimal design of selfanchored cable stayed suspension bridge slingscheme,in accordance with the sling tension principle,Put forward four sets of suspender tensioning scheme,And the four set of program to optimize the comparison, put forward the optimum plan; to provide theoretical basis for similar bridge design and application.
