本文在分析弹性三层、四层体系路面结构基础上,提出了求解这两种路面结构表面弯沉系数的回归公式,分析了柔性路面的结构组合设计;并以文献[3]为基准,建立了用非线性规划方法进行柔性路面结构优化设计的数学模型。从而获得路面结构总造价最低的目标函数。还采用 Flexiplex Tolerance(F-T)法求解了数学模型的最优解,用 FORTRAN-77语言编制了相应的计算机程序(FPOD-4),经计算表明,该程序有收敛速度快及计算精度高的优点。
Based on the analysis of the elastic three-story and four-story pavement structures, a regression formula for solving these two kinds of pavement surface structure deflection coefficients is proposed. The structural combination design of the flexible pavement is analyzed. Based on the literature [3] A mathematical model of optimal design of flexible pavement structure based on nonlinear programming is presented. So as to obtain the lowest total cost of pavement structure objective function. The optimal solution of the mathematical model is also solved by Flexiplex Tolerance (FT) method. The corresponding computer program (FPOD-4) is compiled by FORTRAN-77 language. The calculation shows that the program has the advantages of fast convergence and high computational accuracy .
