刚性路面的优化设计方法研究

Optimum Structure Design of Rigid Pavement

本文应用数学规划方法,分析了刚性路面结构组合设计;以《公路水泥混凝土路面设计规范(JTJ012-84)》为依据,建立了用非线性规划方法进行刚性路面结构优化设计的数学模型,用Flexiplex-Tolerance法成功地求解了数学模型的最优解。根据数学模型和Flexiplex-Tolefance法原理编制的计算机程序分别在HONEYWELLDPS-8和IBM-PC机调试通过。经计算表明该方法收敛较快,精度较高,可供工程设计参考使用。

In this paper, the optimum strueture design of rigid pavement using the method of mathematical programming is studied. The mathematical model is based on the nonlinear programming method and is in conformity with 'Design Rules of Highway Cement Concrete Pavement (JTJO12-84)'. According to the mathematical model and Flexiplex Tolerance method, the programs have heen developed separately for HONEYWELL DPS-8 and IBM-PC computer. The calculated results show that owing to its conditions of covergence and accuracy, the method can be applied to engineering design.
