摘要:: 针对复杂艰险山区铁路近期年客货运量预测接近30 Mt，单线可满足近期运输需要、远期需双线的情况，综合考虑地质地形复杂、投资巨大以及桥梁和隧道修建后改造或预留都会产生大量废弃工程的问题，如何合理的确定线路建设规模和方案成为亟需解决的问题。本文以玉磨铁路玉溪至西双版纳段铁路为研究背景，在运量分析基础上，结合地形、地质条件，从运输能力、车站条件、工程难度、环境保护、社会影响等多方面进行综合分析，最终推荐玉溪至西双版纳段按双线方案建设，可为类似工程提供借鉴。

Abstract:: In view of the conditions that the recent railway passengers and goods transportation volume forecast in complex and dangerous mountainous areas is close to 30 Mt, single line can meet the needs of transport in short-term but in long-term double-line is needed, and taking into account the complex terrain and geology, huge investment and a large number of abandoned construction work created after the bridge and tunnel reconstruction or reservation, how to determine the reasonable line construction scale and scheme becomes an urgent problem to be solved. Based on the analysis of traffic volume, and combined with terrain and geological conditions, this paper comprehensively analyzes the construction scheme of Yuxi-Xishuangbanna section of Yuxi-Mohan railway from the aspects of transportation capacity, station condition, engineering difficulty, environmental protection and social influence, etc., finally, the dual line scheme is recommended for construction of Yuxi-Xishuangbanna section, it can provide reference for similar projects.
