摘要
箱形截面是铁路桥梁中应用比较广泛的截面形式。基于某铁路连续梁的钢箱截面，研究了计入材料弹塑性截面几何特性计算方法，给出了具体的计算公式。基于 Visual Studio2010程序开发平台编制了截面几何特性计算程序，并通过算例进行了验证。提出的计算方法，能为今后类似研究提供参考。
Box section is used widely in the field of railway bridges.Based on the steel box section of a railway continuous beam,the calculation methods of section elastic-plastic geometric properties are studied and the detailed calculation formu-las are given.Based on the Visual Studio2010 application development platform,the elastic-plastic geometric properties calculation program is established,meanwhile,the program calculation results are verified by specific examples.Calcula-tion methods can be referenced by the similar studies in the future.
