摘　　要：峨眉至米易段是成昆铁路扩能工程实施的最后一段,也是地形和地质条件最为复杂的一段。本文结合沿线的地形和地质条件,参考既有铁路地质灾害发生、发育及危害程度等,应用减灾选线的理论和方法,对沿线各类不良地质分类总结并确定相应的选线措施。研究成果可为复杂地质条件下的艰险山区铁路选线提供借鉴。The Emei-Miyi Section is the last section of the capacity expansion of Chengdu-Kunming Railway,and also the one with the most complex topographical and geological conditions.Based on the topographical and geological conditions along the line,consulting the occurrence,development,and degree of harm of geological disasters of existing railways,and applying the theory and method of route selection for disaster reduction,this paper summarized the classification of various unfavorable geological conditions along the line and determines the corresponding measures in route selection.The results can provide a reference for route selection of railways in difficult mountainous areas under complex geological conditions.
