摘　　要：研究目的:结合云南大理至丽江铁路区域地震地质条件复杂、环境保护要求高、铁路选线难度大等特点开展地质选线研究,建立高烈度地震区工地质与环境地质综合选线的技术体系并推广应用。研究结论:(1)系统总结了"高烈度地震区工程地质与环境地质综合选线"原则,并采用遥感判释、地质调绘、物探(电法、地震波法、大地电磁法等)、钻探、孔内测试、原位测试、室内试验等综合勘探技术、地震安全性评估(含活动断裂鉴定)、环境影响评价等方法,构建了一套完整的高烈度地震区工地质与环境地质综合选线的技术体系,具有重要的推广应用价值;(2)通过三大线路方案的地震地质条件、环境敏感区域等综合比选研究,选出了最优的线路方案。经工程建设和运营实践检验,线路方案科学合理,既最大限度地保护了生态环境,又使线路位于"安全岛"内,经济、社会、环境效益显著,被国家环保总局专家誉为"工程地质与环境地质有机结合选线的典范",为类似地区铁路选线积累了经验。Research purposes： For the area of railway from Dali to Lijiang in Yunnan, combining the features of complex seismic geological conditions, highly required environmental protection and difficult route selection therein, the related study is carried out so as to establish, and then promote the technical system for the route selection combining geology and environmental geology for railway engineering in high - intensity earthquake zone. Research conclusions： This paper systemically summarizes the principle of the ＂route selection combining geology and environmental geology for railway engineering in high - intensity earthquake zone＂. By the means of remote sensing interpretation, geological mapping, geophysical prospecting （by electricity, seismic waves, or magnetotellurics etc. ） , drilling exploration, hole testing, in -situ testing, indoor tests and other comprehensive prospecting technique, as well as seismic safety evaluation （including active fault identification）, environmental effect appraisal, this complete system is constituted, which has an important value to promote. An optimal route scheme is selected through overall comparison among three schemes from the aspects of seismic geological conditions and environmental sensitive area, and then verified by engineering construction and practical operation to be scientific and reasonable, which not only protects the ecological environment to a maximum extent, but also includes the route into a ＂ safe island ＂. With outstanding economic, social and environmental benefits, it is praised by experts from the Ministry of Environmental Protection as the ＂ Example of Route Selection Combining Engineering Geology and Environmental Geology Organically＂, accumulating experience for railway route selection in similar region.
