摘　　要：山区线路选线时,需要综合考虑工程投资、规划结合、环境影响、地形地质条件等因素。一个合理的线路方案可用最小的经济投资换取最大的工程效益。以集通铁路扩能改造工程中蒙根塔拉至林西越岭段落线路方案为例,重点探讨了限制坡度、线路走向的选择及越岭隧道对线路方案的影响,结合实例分析提出了部分可供后续项目借鉴的思路。When selecting route of railways in mountainous area,it is necessary to consider comprehensively such factors as project investment,combination of planning,environmental impact,topographic and geological conditions,etc. A reasonable route scheme can exchange the smallest economic investment for the greatest engineering benefit. In this paper,taking the line scheme of Linxi Mountain Crossing Section in Jitong Railway Expansion and Renovation Project as an example,the selection of limit gradient and route direction,as well as the influence of over-mountain tunnel on the line scheme are emphatically discussed. Based on the case analysis,some ideas which can be used for reference by subsequent projects are put forward.
