西延高铁铜川北站站位方案研究

Comprehensive Line Selection for Tongchuan North Station of Xi’an-Yan’an High-speed Railway under Gully-Liang-Mouth Terrain

西延高铁是“八纵八横”铁路网中包(银)海通道的重要组成部分。在铜川北站的选址方案研究中,受煤炭采空区、沟壑梁峁地形等因素的制约,车站的选址及布设极其困难。在符合铜川市城镇规划和交通网络规划,满足运输需求、车站分布和线路主要技术标准的原则下,从经济性和站位优缺点两方面对车站选址进行详细的方案比选研究,推荐了适应地形且满足城市规划发展的王家河工业园区站位。此外,研究了不同高程的车站方案,最终确定以降低桥高、塬头挖方的形式设站,解决了沟壑梁峁地形下设站难的问题。

Xi'an-Yan'an high-speed railway is an important part of Baotou(Yinchuan)to Haikou high-speed railway.During the process of location selection of Tongchuan North Railway Station,it is extremely difficult to locate and lay out the station because of the restriction of the line direction in the coal mined-out area and some constraint factors such as large fluctuation,deep valley and unstable slope in gully-liang-mouth Terrain.Firstly,this essay compares and studies the location of station in detail from the aspects of economy and station's advantages and disadvantages,and recommends the location in Wangjiahe Industrial Park which is more suitable for terrain and meets the development of urban planning;Secondly,this paper studies the station schemes with different elevations by considering the effects of engineering settings and bad geology.It helps to finally determines the form of reducing bridge height and excavation of Plateau head,solving the problem of difficult stations under gully and ridge topography,and has certain reference significance for comprehensive route selection of stations under similar topography.It approaches the principle of urban planning and transportation system of Tongchuan,achieving the demands on transportation and meeting the technical principle of railway and station contribution.
