蒙西至华中地区铁路五里川至邓州段线路方案研究

Study on Route Alignment of Wulichuan-Dengzhou Section of the Railway from the West Inner Mongolia to the Central China

五里川至邓州段铁路的修建将使本地区资源优势迅速转化为经济优势,因此设计出线路短、工程小、投资小的铁路方案,对促进区域内经济发展和完善路网结构均具有十分重要的意义。通过对蒙西至华中地区铁路线位走向的研究,针对路网规划,功能定位,接轨和线路走向,地质选线,环保要求,地方经济发展特点等影响因素,对五里川至邓州段线路进行了沿既有线、既有线北侧和既有线南侧3个方案的分析和探讨,经综合比选提出了五里川至邓州段采用沿既有线方案作为推荐方案的建议。

The Wulichuan-Dengzhou railway section will help to turn the local resource advantage into economic advantage quickly. Therefore, for this railway section, it is significant to design a good scheme with short route, small scale and low cost, so as to promote regional economy development and perfect the structure of railway network. After studying the route alignment of the whole railway, which is from the west Inner Mongolia to the Central China, this paper emphatically analyzed the main influence factors, such as railway network planning, function orientation, track junction and alignment, geological route selection, requirement of environment protection, regional economy development characteristic and so on. On this basis, for the Wulichuan-Dengzhou railway section, this paper analyzed and discussed three schemes of route alignment respectively as follows： along the existing line, on the north side of the existing line and on the south side of the existing line. Finally, by means of comprehensive comparison and selection, the scheme of along the existing line was proposed as the recommended scheme for the route alignment of Wulichuan-Dengzhou railway section.
