摘要
介绍以既有轨面测点数据为基础形成初始纵断面，以轨面抬降量加权和为目标函数，采用动态规划法原理进行纵断面优化设计的方法。实例验算表明其优化效果显著。且目标函数的改变对优化程序和优化速度的影响不大。
The paper presents a method of longitudinal section optimization design with dynamic program principle based on the objective function of the coefficient sum of lifting and cutting amount and initial profile which is formed by the existing track surface survey data. A computer program has been completed and some practical examples have been calculated. The result is rather satisfactory. The optimization program and speed are little influenced when the objective function is changed.
