摘要
通过对比分析国内外已建和在建的多塔斜拉桥刚度提高措施,从辅助墩设置、桥塔及主梁刚度调整、拉索体系确定、桥跨布置、支座形式、采用部分斜拉桥等几个方面分析各种措施对提高斜拉桥体系刚度的影响。
In this paper, rigidity -improving methods of multi - tower cable - stayed bridges built and under construction including domestic and overseas are compared and analyzed. The following aspects which will influence the system rigidity of cable - stayed bridge have been analyzed ： auxiliary pier installing, rigidity adjustment of tower and girder, cable system assertion, span arrangement, bearing form and adopting partial cable - stayed bridge, etc.
