摘　　要：中尼铁路作为世界上首条穿越喜马拉雅山脉的铁路工程,面临着高海拔、高落差、高寒气候、地震活动带、软岩变形、不良地质发育等诸多环境、地质问题,线路方案的设计、选择明显受地质条件的约束,需要彻底摸清区内各类地质问题。为了克服地表调查的局限性、减轻外业调查工作量、提高工作效率,文章充分发挥遥感技术特长,在分析已有基础地质、工程地质、地质环境等资料的基础上,采用多源遥感技术,对研究区内的地形地貌、地层岩性、地质构造、水文地质、滑坡、泥石流、风沙等不良地质要素开展了详细的解译分析,为工程地质调查以及线路方案设计、选线提供了较详细、全面、可靠的遥感成果资料,发挥了重要的技术支撑作用。As the first railway project crossing the Himalayas in the world,the construction of the China-Nepal railway is confronted with many environmental and geological problems such as high elevation,a big difference in elevation,alpine climate,seismic activity zones,soft-rock deformation,and geological disasters.Since the design and selection of route schemes of the railway line are notably restricted by geological conditions,it is necessary to thoroughly understand various geological problems in the study area.This study gives full play to the remote sensing technique to overcome the limitations of surface surveys,reduce the workload of field surveys,and improve work efficiency.Based on the analyses of existing data on basic geology,engineering geology,and geological environment,this study uses the multi-source remote sensing technique to conduct a detailed interpretation and analysis of the adverse geological elements in the study area,including terrain,landform,stratigraphic lithology,geological structures,hydrogeology,landslides,debris flow,and wind-blown sand.In this way,it provides detailed,comprehensive,and reliable remote sensing data for the engineering geological survey and the route design and selection of the China-Nepal railway and plays an important role in technical support.
