贵阳至南宁高速铁路环保选线设计探讨

Discussion on Environment-friendly Railway Location Design of Guiyang-Nanning High-speed Railway

随着国家“补短板”、“惠民生”和“交通强国”战略的推进,中国高速铁路路网正逐步由平原丘陵地区向山区拓展,加之山区具有地形地貌复杂、地质灾害频发、生态功能重要、生态环境敏感脆弱、环境敏感区交织密布等特征;通过环保选线,从源头上减少对环境的影响,实现铁路发展和环境保护协调统一,进一步促进沿线经济发展。本文通过贵阳至南宁高速铁路环保选线设计实践,总结出山区铁路环保选线设计原则,可为类似铁路提供借鉴。

With the promotion of the national strategies of"Bolstering weak spots and benefiting the people,"and"Building National Strength in Transportation",China s high-speed railway network is gradually expanding from plain and hilly areas to mountainous areas,and the mountainous areas are characterized by complex topography and landform,frequent geological disasters,important ecological functions,sensitive and fragile ecological environment,and densely interwoven environmentally sensitive areas.With an environment-friendly railway location design,the impact on the environment is reduced from the source,the coordination and unification of railway development and environmental protection are realized,and the economic development along the railway is further promoted.Through the practice of environment-friendly railway location design for Guiyang-Nanning High-speed Railway,this paper summarizes the principles of the environment-friendly railway location design for mountainous railways,providing a reference for similar railways.
