摘　　要：选线设计作为铁路工程设计的关键环节,选线方案的优劣某种程度上决定着工程可行性和工程投资。铁路线位走向受众多因素制约,艰险山区铁路选线则更为困难,常常造成重复返工和修改,增加线路方案确定的时间成本。本文以西北地区某山区铁路为例,分析了复杂山区铁路选线的关键控制因素,凝练复杂山区铁路选线的一般实践方法,旨在帮助铁路选线实践中,减少方案修改遍数,推荐最优方案,提高铁路选线效率。As a key link in railway engineering design,the quality of the route selection scheme to some extent determines the feasibility and investment of the project.The direction of railway route is constrained by multiple factors,and the selection of railway route in difficult mountainous areas is even more difficult,often resulting in repeated rework and modifications,increasing the time cost of determining the route plan.This article takes a railway in a mountainous area in the northwest region as an example to analyze the key control factors of railway route selection in complex mountainous areas,condense the general practical methods of railway route selection in complex mountainous areas,and aim to help reduce the number of scheme modifications,recommend the optimal scheme,and improve the efficiency of railway route selection in railway practice.
