随着计算机技术的广泛应用,现代数学的新成就在黄土的科研、生产中加速渗透,并取得 了明显的效果。本文试图借助于计算机这一新技术,对黄土地区铁路工程地质问题进行分析评价。因铁路是条带状分布的,一条长大铁路有可能涉及到不同地区的工程地质问题。所以,我们没有刻 意研究某一地区的黄土评价问题,而是从黄土的共性出发，总结归纳工作中所遇到的各类型黄的 土的特征、评价方法及改良措施，建立黄土地区铁路工程地质数据库，并摹拟专家评价黄土地区铁 路建筑场地的过程，编制了计算机程序系统。本文重点介绍该评价系统实现的思路、依据及方法，最后给出几点体会.

With wide use of computer technic,new mathematics achievements spread quickly in the research and production of the loess and obvious effect has been obtained. With com?puter?the author tries to analyse and evaluate the problems of railway engineering geology in loess area. Because of the strip distribution,a long railway may meet different questions in different areas. Thus,in stead of researching the ealuated proble, of loess in someone area， the author begins with the common characteristics of loess,sums up the charateristic,evalu?ated methods and ways of all kinds of loess,founds the data base on railway engineering geol?ogy in loess area,imitates the process in which experts evaluate the railway site in loess ares. And a computer evaluated system is made at last. The train of thought，basement and method of the evaluated system are imtroduced in this article,and some suggestions are given in the end.
