目前优化铁路纵断面的方法中,有些程序常常依赖于人工赋给的初始纵断面,如何进一步用机器自动产生初始纵断面成为我们关注的问题。由于铁路设计的错综复杂,致使铁路初始纵断面的自动产生同样比较繁琐。本文主要在学习国外资料和各兄弟院校的方法的基础上,制定一套较为简便,较为可行的方法,用来产生初始纵断面,以供优化设计时使用。 At present, among the methods for optimizing the longitudinal section of the railway, some programs often rely on the initial artificial sections that are manually assigned. How to further automatically generate the initial longitudinal section with a machine becomes a concern of us. Due to the intricacies of railway design, the automatic generation of the initial railway profile is also more complicated. This paper, based on the study of foreign materials and the methods used by various universities, makes a relatively simple and feasible method for generating the initial profile for use in optimizing the design.
