摘　　要：中巴经济走廊是“一带一路倡议”的先试区和重点项目区,拟建中巴铁路是其重要组成部分,但铁路行经的喀喇昆仑山脉为全球山谷冰川最发育的区域,我国尚无在冰川区修建铁路的经验。鉴此,以中巴经济走廊Gilgit至Khunjerb段为研究区,研究沿线大陆性冰川、海洋性冰川和跃动冰川的分布以及各类冰川的活动性特点,定义冰川直接作用区和间接作用区且分析相应的成灾模式,并据此提出选线要点;最后针对中巴铁路沿线四大冰川群,分别提出选线设计建议。研究成果对冰川区铁路选线设计具有普适性指导意义。China-Pakistan Economic Corridor is a pilot and key project of“The Belt and Road”,and the proposed China-Pakistan railway is an important part of it.However,Karakoram is the most developed mountain glacier area in the world,and China has no experience of building railway in the glacier area.Therefore,the section from Gilgit to Khunjerb of China-Pakistan Economic Corridor was selected as the study area.In the first place,distribution of continental glaciers,marine glaciers and active glaciers along the route was determined,and then,definition of direct and indirect impact areas were given,according above two areas,the disaster modes were analyzed to present the railway location points.At last,for four glacier groups along the railway line,we put forward the concrete railway location strategies,respectively.The findings could provide general guidance for railway alignment design in glacier areas.
