太兴铁路穿越吕梁山段越岭方案研究

Research on Route Selection for Taiyuan-Xingxian Railway Passing through Lvliang Mountain

为确定太原至兴县铁路穿越吕梁山脉的方案,设计人员进行了大范围的线路比选。通过对工程所经地区控制选线的因素进行说明,结合地方规划和环境敏感点等着重选取沿湫水河的大石林沟垭口方案和沿蔚汾河的野鸡山垭口方案进行研究,从工程规模、工程投资、地方规划、环境保护等方面进行比较分析,最终确定沿湫水河的大石林沟垭口方案为合理越岭方案。通过对越岭方案研究过程进行论述,提出了一种设计思路,可为类似工程提供一定的借鉴作用。

Civil engineers have conducted extensive researches on the route selection of Taiyuan-Xingxian Railway passing through Lvliang Mountain. Based on the control factors in route selection,such as local planning and environmental sensitive sites and so on,this paper studies the following two schemes： one is to pass through Dashilingou pass along Qiushuihe River,and another is to pass through Yejishan pass along Weifenhe River. Analysis and comparison are conducted in terms of project scale,project investment,local planning and environmental protection. It is concluded that the scheme of Taiyuan-Xingxian Railway passing through Dashilingou pass is the best one. This paper proposes a new design concept with details in crossing-mountain design process,which may provide reference for similar projects.
