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.
