摘要
研究目的:铁路选线是铁路设计中最根本、最重要的工作,是影响全局性的总体工作。随着铁路技术标准的提高和高桥、长隧修建技术的提高,铁路选线理念发生了较大变化,高速路选线设计更加注重工程安全、更加注重环境,城镇规划,资源开发、交通、农田、水利设施间的协调,要求总体上相互配合,全局上经济合理,更多地采用高新技术,这也是世界一流高速铁路、客运专线的总体设计要求,为此,线路选线的质量将直接关系到铁路工程建设的可靠性、安全性、技术可行性和经济合理性及社会接纳性,关系到铁路和地方经济社会的发展,因而它是高速铁路建设应重视的首要问题,只有树立正确的选线理念,才能建设世界一流的高速铁路。研究结论:本文简述了高速铁路选线的主要制约因素,提出了坚持地质选线、重大工程优先选址、环保选线、规划选线、资源选线、横断面选线,六位一体的选线原则理念,并强调在确定线路走向时要做到失小得大,对重点线路与非重点线路区别对待,做到合理配置资源,避免浪费。在线路方案比选中,要高度重视投资控制,但不能把投资作为唯一的要素考虑。只有投资合理、社会综合效益最大化的线路方案才是最优方案。
Research purposes： Railway location is the most fundamental and important work in railway design, which is the overall work affecting the whole. Along with the improvement of railway technology standards and building technology of high bridge and long tunnel, great changes have taken place on the railway location concept. For high - speed railway location design, more attention should be paid to engineering safety, environment and urban planning as well as coordination of resource development, traffic, farmland and water conservancy facilities between each other, overall coordination with each other and globally economic rationality with more high and new technology applied shall be required, which is the overall design requirements for world - class high - speed railway and passenger dedicated line as well. In this respect, the quality of route location shall directly affect reliability, safety, technical feasibility, economic rationality and social admissibility of railway construction as well as development of railway and local economic sociality. It is therefore the first question to be valued for high - speed railway construction. Only proper route location concept established, world- class high -speed railway can be constructed. Research conclusions：Connecting with the main restraining factors to route location of high - speed railway, the route location principle concepts including geological location, priority site selection to major project, environment protection, planning, resource and cross - section route location have been put forward in this paper, which emphasizes focusing on the major and free the minor while determining the alignment of railway, making a difference between key route and nonessential route, allocating the resources rationally to avoid controlled but not the sole factor taken into account. None but In route alternative, investment should be strictly the route scheme with proper investment and optimization of social comprehensive benefit shall be optimal scheme.
