摘要
复杂艰险山区,因为地形艰险、地质复杂,潜在地质灾害风险,如何准确识别地质灾害,采取相应的地质灾害防范措施,避免或减轻地质灾害,是复杂艰险山区铁路选线更为重要的工作内容和工作目标。在分析"崩滑流"区、岩溶山区、地震山区以及链式灾害区潜在的地质灾害风险,及其对铁路的突出危害的基础上,提出以规避重大地质灾害风险为目标的复杂艰险山区铁路减灾选线6大基本准则。
Potential geological disaster risk is in complicated and dangerous mountainous areas due to the difficult and dangerous terrain and complicated geology,therefore,how to accurately identify the geological disaster,take the corresponding geological disaster prevention measures to avoid or mitigate geological disaster are the more important works and aims of route selection in complex dangerous mountain railway.This paper puts forward six basic criteria for disaster reduction techniques of railway route selection in complex dangerous mountain areas aiming at avoiding major geological hazard risks based on the analysis of potential geological hazard risks in"landslide flow"area,karst mountain area,earthquake mountain area and chain disaster area,as well as their prominent hazards to railway.
