| 摘 要： | 利用三次样条函数来逼近合理拱轴线,基于MATLAB语言对钢管混凝土拱桥拱轴线进行优化,优化后的结点最大偏离量比优化前的最大偏离量减小了25.0％,效果较明显,也改善了拱的内力分布情况。分析表明,该法只需编写比较简单的程序代码,即可简便求出设计变量的最优解,且结果可靠,计算效率高。

| Abstract: | With cubic spline function approaching the rational arc axial line,this paper optimizes arc axial line of concrete-filled steel tubular arch bridge based on MATLAB language.The maximum node departure after optimization is 25.0% less than that before optimization,which obtains obvious effect and improves internal force distribution of arc.Analysis indicates that this method only requires simple program code to seek for the optimal solution of design variable with reliable result and high calculation efficien... |
