摘　　要：大丽线位于陆缘拗褶带,地质构造恶劣,选线因素复杂。根据大丽线的选线设计实践,对该线路的地质和环境综合选线的原则、设计思路进行归纳总结,经大量的分析研究,从3个比选方案中甄选出对环境影响最小、工程设置最为合理的线路方案,从而规避了工程风险,确保了工程的顺利实施。As located in epicontinental folded downwarping region, the geological structure of Dali-Lijiang railway is such unfavorable and the route location, therefore, is complicated. Based on the route location and design practices of Dali to Lijiang Railway, this paper summarizes the principles of comprehensive route location and design ideas on geology and environment of this railway, and through those analyses, one of the three alternatives has been selected with which the line has the minimum environment influence and rational engineering arrangement. Thereby, the engineering risks are evaded and smooth construction is ensured.
