某三塔双跨空间索面人行索桥总体设计要点与分析
|
摘要
江西庐山西海玻璃桥采用三塔双跨空间地锚式悬索结构,主缆跨度为199.567m+214.934m,加劲梁跨度为144.088m+183.043m。桥塔采用箱型钢塔柱,桥面采用全透明夹胶钢化玻璃,中间设置圆形观景平台与摩天轮。本文论述了该桥的缆索体系、主塔、加劲梁的设计要点,以及相应的总体计算与各构件的计算结果,为该类人行悬索桥的设计与施工提供一定的参考。
Xihai Glass Bridge which is located in Lushan, Yongxiu, Jiangxi Province adopts three-tower and two-span space anchored suspension structure. The main cable span is 199. 567 m +214. 934 m, and the stiffening beam span is 144. 088 m + 183. 043 m. The bridge tower adopts box steel tower column, the bridge deck adopts transparent toughened glass with glue, and a circular viewing platform and a ferris wheel are set in the middle of the bridge. This paper discussed the main points of the design of the cable system, main tower and stiffening girder of the bridge, as well as the corresponding overall calculation and the calculation results of each component, which can provide some reference for the design and construction of this kind of pedestrian suspension bridge.
