为研究中央扣对不同悬吊结构体系悬索桥受力的影响，文章以西堠门大桥为背景，采用西南交通大学编制的桥梁非线性计算软件BNLAS建立了计算模型，模型中主缆的跨度为578 m +1 650 m +465 m。通过比较加劲梁不同的支承形式分析中央扣对悬索桥受力的影响。
In order to study the influence of central buckle in suspension bridge on different suspension systems, this paper took Xihoumen suspension bridge as an example, established its finite element model with main cable span of (578+1 650+465) m by using bridge nonlinear analysis system BNLAS, which was developed by Southwest Jiaotong University. Then, it analyzed the influence of central buckle on suspension bridge's structural performance with different supporting forms.
