西康高铁引入安康铁路枢纽方案研究

线路引入枢纽方案是铁路选线的一大重点,尤其是对于比较复杂的枢纽而言。为了研究西康高铁引入安康铁路枢纽的合理方案,运用逐层深入、从宏观到微观的分析方法以及多种方案综合比选手段,从项目功能定位入手,在仔细分析安康铁路枢纽概况、安康市城市总体规划及交通规划、枢纽客运量的基础上,首先对西、中、东三个线路走向方案从技术经济角度比选论证,得出推荐中线方案;然后针对中线方案,研究引入既有安康站和新设安康北站两个方案,得出推荐新设安康北站方案;最后针对动车存车场选址研究站对左、站同右两个方案,得出推荐站对左方案。本次研究提出了"线路+站场"组合思路。

Study on Scheme of Introducing Xi'an-Ankang High-Speed Railway into Ankang Railway Hub

The scheme of introducing a railway into a hub is a focus for railway route selection,particularly for the more complex hub. In order to study the reasonable solution of introducing Xi 'an-Ankang high-speed railway into Ankangrailway hub,this article uses step-by-step and macro-to-microscopic analysis methods and multiple comparison and selection methods to analyze the general layout planning of Ankang railway hub,Ankang City's overall urban planning,transportation planning and hub passenger traffic based on functional orientations. First of all,the schemes of the west,middle and east lines are compared and demonstrated from the technical and economic perspectives,and the midline is recommended. Then,for the midline option,two introducing plans of existing Ankang Station and newly-established Ankang North Station are studied and the newly-established Ankang North Station is prioritized. At last,the study of the left and right options as the train parking yard favors the first one. This study proposes the combination concept of track-line plus yard.
