摘　　要：采用有限元方法,对钢系杆拱各种矢跨比、拱梁刚度比、拱肋平面倾角、吊杆及其他主要杆件截面形式、主桁中心距、横向连接、桥面形式等进行计算,得出不同结构参数下的钢系杆拱的优缺点,提出了适合于福厦铁路实际情况的合理结构形式和设计参数。The finite element method is used to make calculation of various rise/span ratios,arch/beam rigidity ratios, arch rib plane inclination angles, sectional shapes of hangers and other primary elements, c/c distances of main trusses, lateral connection and deck types of the steel box tied arch bridge. The advantages and disadvantages of the steel box tied arch bridge with different structural parameters are obtained and rational structural form and design parameters of the arch bridge adaptable to the specific conditions of Fuzhou-Xiamen Railway are put forward.
