西安至十堰高铁穿越秦岭段饮用水源地环保选线研究

Study on Environmental Protection Route Selection of Drinking Water Source A Case Study of Xi'an-Shiyan High-speed Railway through Qinling Mountains

秦岭山区自然环境良好,生态敏感区众多,结合沿线区域地质条件、工程条件设置、环境保护等因素,综合比较分析西安至十堰高铁对李家河水库饮用水源地的影响,通过多种设计方案研究结果,推荐以隧道方式穿越李家河水库饮用水水源地准保护区的线路方案,该方案既保证了沿线居民的供水不受影响,并且对区域其他生态敏感区的影响降到最低限度。通过该工程选线研究总结了铁路工程穿越多个环境敏感区时的选线原则、方法及体会,保护了秦岭山区的水生态环境,为秦岭山区类似工程选线设计提供参考。

The Qinling mountainous region has a good natural environment and many ecologically susceptible areas.Combined with regional geological conditions,engineering settings,environmental protection and other factors,a comparative analysis of the impact of the Xi'an-Shiyan high-speed rail crossing the drinking water source of Lijiahe Reservoir is carried out.It is recommended to use a tunnel to cross the quasi-protected area of the drinking water source of Lijiahe Reservoir through a variety of design schemes.The route plan of the reservoir quasi-protection area,which ensures that the water supply of residents along the route is not affected,the aquatic ecological environment of the Qinling Mountainsand is protected,and the impact on other ecologically sensitive areas in the region is minimized.This article summarizes the principles,methods and experience of route selection when high-speed train pass through multiple environmentally susceptible areas,and provides references for the design of similar projects in the Qinling Mountains.
