摘要:: 中尼铁路是中尼两国为构建中尼面向发展与繁荣的世代友好战略合作伙伴关系而启动的重大基础设施，是跨喜马拉雅立体互联互通网络的骨干。中尼铁路地处高原、高寒地区，线路位于印度板块与欧亚板块碰撞、拼合带内，穿越喜马拉雅山脉，地形地质条件复杂，因此需深入研究，合理选择过境通道。本文对可能的过境通道方案进行了研究，重点研究了聂拉木（樟木）通道和吉隆通道方案，并从线路长度、工程地质条件、对环境影响、重点工程条件及风险、口岸站设置条件、口岸开发及贸易条件等方面进行综合分析。结果表明，聂拉木（樟木）通道方案新建长度短，对环境影响较小，吉隆通道方案的口岸站设置条件相对较好，两方案各有优劣，下阶段需结合详细勘察资料、地方意见等进一步研究。

Abstract:: China-Nepal Railway is a major infrastructure initiated by the two governments to build China-Nepal Strategic Partnership of Cooperation Featuring Ever-lasting Friendship for Development and Prosperity, and it is the backbone of the trans-Himalayan three-dimensional interconnection network. China-Nepal Railway is located in the plateau and arctic-alpine area. The line is located in the collision and splicing zone between the Indian Plate and the Eurasian Plate. It crosses the Himalayas, and the terrain and geological conditions are complex. Therefore, it is necessary to conduct in-depth research and reasonably select the cross-border passages. In this paper, the possible plans of cross-border passages are studied, focusing on the plans of Nyalam (Zhangmu) Passage and Gyirong Passage, and comprehensive analysis is made from the aspects of line length, engineering geological conditions, environmental impact, key engineering conditions, and risks, port station setting conditions, port development, and trade conditions, etc. The results show that the newly-built length of the Nyalam (Zhangmu) Passage is short and has little impact on the environment. The port station setting conditions of the Gyirong Passage are relatively good, and both plans have their own advantages and disadvantages. In the next stage, further research is needed in combination with detailed survey data and local opinions.
