高速铁路选线对生态环境的影响分析研究

高速铁路选线要充分考虑对生态环境的影响,在路基、桥涵、隧道等形式通过环境敏感点时,要从工程技术和生态环境保护的角度出发,避免高速铁路建设和运营对当地的水资源环境、自然保护区造成破坏。根据高速铁路周边的环境信息,在路基填土高度上结合地形、地质和水文自然特征确定合理的填土高度。在高速铁路跨越生态保护区和湖泊等线路中,贯彻生态选线的原则,准确确定桥涵净空,在工程设计、施工上采用系列的生态保护措施。

Analysis on Influence of High-speed Railway Line Selection on Ecological Environment

The high-speed railway line selection should fully consider the impact on the ecological environment. In the envi-ronmental sensitive points like roadbed,bridge,tunnel,it's necessary to avoid the damage of high speed railway construction and operation on local water resources environment and nature reserve from the point of view of engineering technology and ecological en-vironment protection. According to the high-speed railway surrounding environmental information,the embankment fill height com-bined with the terrain. The geological and hydrological characteristics determine the reasonable fill height. In the high-speed rail-way crossing over ecological protection areas and lakes,the principle of ecological route selection is carried out,the bridge and cul-vert clearance is accurately determined,and the engineering design is carried out. A series of ecological protection measures are a-dopted in construction. The selection of high-speed railway lines should fully analyze the status quo,sensitivity and influencing factors of regional ecological environment in order to create a high-speed railway line in which man and nature coexist harmoniously.
