| 摘 要： | 滇西北地区位于青藏高原面的边缘及河谷斜坡地带,由于地壳的大面积隆升、断裂作用和强烈的流水侵蚀、溶蚀,形成独具特色的高原岩溶。以丽香铁路为依托,在岩溶水文地质调查的基础上,论述岩溶地貌类型、岩溶及岩溶水的发育规律,分析岩溶对隧道工程影响,为隧道工程的设计、施工提供科学依据,研究结论对高原岩溶区的工程建设具有指导意义。

| Abstract: | The area of northwest Yunnan,located at the edge of Qinghai-Tibet plateau and in the valley slope zone,is unique for plateau karst due to the uplift of large area of earth's crust,faulting and heavy water erosion and corrosion.The types of karst landform,development law of karst and karst water related to the Lijiang to Shangri-la railway are discussed based on the survey of karst hydrogeology,and the impact on the tunnel engineering is analyzed.The results could provide a scientific basis for the design and construction of the tunnel and have guiding significance for engineering construction in karst area on the plateau. |
