新疆巴伦台至开特勒铁路关键技术标准研究

Research on Key Technical Standards for Baluntai-Kaitele Railway in Xinjiang

研究目的:新疆巴伦台至开特勒铁路位于高海拔地区,山高坡陡、地形条件复杂,拟建隧道大多为长大隧道,且连续设置。如何合理地选择牵引种类、限制坡度、牵引机型及牵引质量等铁路主要技术标准,直接影响到工程投资,甚至关系到工程的可实施性。本文旨在找出适合于本线的主要技术标准,为类似项目的研究提供参考。研究结论:(1)对不同牵引种类进行分析论证,推荐采用电力牵引;(2)在分析本线功能定位、运量特征等情况的基础上,提出了本线应采用均衡坡度方案,推荐重车方向采用6‰、轻车方向采用22‰的限制坡度;(3)为满足列车牵引质量及输送能力的要求,并考虑与相邻路网的协调匹配,及充分利用其维修养护等设备,本线牵引机型推荐采用SS7型电力机车,牵引质量推荐采用3 000 t;(4)本线拟推荐采用的主要技术标准方案可实施性强、节省投资;(5)研究成果能够为山区复杂地形条件下铁路主要技术标准的选择积累经验。

Research purposes： The Baluntai - Kaitele Railway in Xinjiang is located in the high elevation area with high mountain, steep slope and complex topographical conditions. The most of planed tunnels for the railway will be the large tunnels with one after another. Selection of the reasonable main railway technical standards, such as traction type, limited gradient, locomotive type and tractive tonnage, is crucial to the construction investment and the project operation. In this paper, the suitable main technical standards for this railway are presented for providing the reference to the similar works. Research conclusions： （ 1 ） Based on the analysis of the various types of traction, it is recommended to use the electric locomotive. （2） Based on the analysis of the railway function orientation and the features of the traffic volume, it is recommended to adopt the balanced gradient scheme. Namely, the 6%v limited gradient will be used for the heavy - haul direction and the 22%~ limited gradient will be used for light - haul direction. （3） In order to meet the demands of the tractive tonnage and the traffic capacity of this railway, it is recommended to use SS7 locomotive with the tractive tonnage of 3000t on consideration of the coordination with the adjacent railway network and making full use of the maintenance devices. （4） The demonstrations of the traffic security and the adaptability of the traffic organization show the main technical standards used for this railway are good in the operation and saving the construction investment. （5）The research result can be as the basis for the selection of the main technical standards for the mountain railway with the complex topographical conditions.
