Several Principles of Route Selection for Anshun-Puan Section of High-speed Railway

铁路选线是铁路设计中最根本、最重要的工作,是影响全局的总体性工作。文章简要分析了高速铁路选线的影响因素及几个主要原则,并结合长昆客运专线安顺至普安段的选线实践,研究贯彻环境选线、地质选线、重大工程优先选址及坚持综合最优等选线原则的具体做法,探索了艰险困难山区高速铁路的选线技术。

Railway route selection is the most fundamental and important work in railway design, which is the overall work affecting the whole. Based on the briefly analysis of the influencing factors and several main principles of the high- speed railway route selection and combination of the route selection of Anshun-Puan section on Changsha-Kunming PDL, and the route selection principles of the environmental route selection, geological route selection, major engineering pri- ority select location and adhere to complex optimal and so on, this article explores the technology of route selection of high-speed railway in the dangerous difficult mountainous areas.
