摘要
本文对铁路线路平面、纵断面整体优化设计进行研究探讨.建立了问题的数学模型.在带状数字地型模型的基础上,对平面交点坐标、曲线半径和纵断面设计标高进行优化.借助工程师的设计思想,对优化设计中的一些实际问题采取人机交互的方式处理.经实际线路的计算表明所建模型是正确的,采用的处理方法是可行的,优化设计的经济效益是明显的.
This paper studies the overall optimal design of horizontal andvertical alignment of railway.A mathematical model for suchpurpose is set up.Based on the strip DTM we take the coordinatesof intersection point,radii of curve and levels of profile as thedesign variables and optimize them with nonlinear program technique.With the aid of experience of engineer in computing processingsome practical problems are solved by the way of man-computerinteraction.The compution results of pratical lines show that themathematical model set up is correct,the method employed isfeasible and the economic profit is obvious.
