钢管混凝土拱桥拱轴线的计算机辅助设计

Computer Aided Design of Arch Axis of Steel Tubed Concrete Arch Bridge

通过对大量已建成钢管混凝土拱桥的统计分析 ,结合三次B样条插值的数值处理方法 ,提出一种实用的钢管混凝土拱桥拱轴线计算机辅助设计方法 ,并编制了相应的计算程序 。

Based on the analysis of about one hundred steel tubed concrete arch bridges, this paper brought forward an applied computer aided arch axis design method for steel tubed concrete arch bridge by numerical mathematics method, and compiled a corresponding calculating program using MATLAB.The method is proved to be simple and effective by example calculating.
