摘　　要：为提高线路方案主要技术标准的设计决策水平,采用GIS二次开发技术建立铁路主要技术标准案例库,从自然属性和社会属性考虑影响主要技术标准选择的各因素作用,构建主要技术标准的多维空间相似决策模型及算法,实现了基于多维空间相似理论的主要技术标准选定方法。通过新建天陇铁路对研究方法进行了验证,应用结果表明:基于GIS的线路主要技术标准案例库,可实现案例的有效管理和筛选分析,该设计方法充分挖掘了技术标准与沿线地理环境的内在相互关系,通过利用既有案例提高了线路主要技术标准设计决策的合理性,可为今后线路方案的智能化设计提供参考。In order to improve the design and decision-making efficiency of railway’s main technical standards,the case base of main technical standards of railway is established by using GIS secondary development technology.Considering the action of every factor affecting the main technical standards selection in terms of natural and social attributes,the decision-making model and algorithm of multi-dimensional space similarity of main technical standards are established.The selection method of main technical standards based on multi-dimensional spatial similarity theory is realized.The method is verified based on the Tianshui-Longnan Railway.The application results show that the effective management and matching of case base of railway’s main technical standards based on GIS could be realized.This design method fully explores the internal relationship between the technical standards and the geographical environment along the railway,and improves the design rationality of the main technical standards of the railway by using the existing cases,which can provide some reference for the intelligent design of future route schemes.
