    In this paper, study is made on the combined optimization design for the plan and profile of new railway line within the surveying belt in hilly countries, and a new RDB method that organically integrates the random search, dynamic programming and B spline function methods together is presented. The paper gives an explanation of the mathematical theory of this method and on how to solve the problem of automatic optimization of railway line within parts of an area.According to the principle of the RDB method, a set of plan and profile combined optimization programs in parts of hilly conntries is worked out, and tests on automatic optimization design are carried out with desired and satisfactory results. It is opined through analysis that the RDB method has the advantages of multitudinous alternative schemes for comparison and selection, rapid optimization speed, direct connection with the strip numerical contour model and saving of large amount of manpower and material resources.

    本文对丘陵地区新建铁路在带状区域内的平纵断面联合优化问题进行了研究,根据所要解决的问题提出了一种新方法——RDB(Random Search—DynamicProgramming—B-spline Methods)方法。这种方法是把随机搜索法、动态规划法和B样条函数法有机地联系在一起的一种方法。本文介绍了这种方法的数学理论和如何解决在局部区域内的线路自动优化问题。根据RDB方法的原理,编制了一套丘陵地带局部区域内平纵断面联合优化程序,并进行了自动优化设计试验,得到了预期的、命人满意的效果。通过分析认为,RDB方法具有比选方案多,优化速度快,能直接与数字地形模型连接,大量节约人力、物力等优点。
