摘　　要：山区铁路选线经历了由"地形选线""地质选线"到"减灾选线"的三大发展阶段。减灾选线,从系统工程出发,更加关注铁路全寿命周期的工程与运营安全,更加关注影响铁路工程与运营安全的灾害风险的识别与防控,更加强调从工程建设源头——工程设计环节,做好风险规避、风险防控工作。减灾选线三大技术工作,包括:灾害识别、智慧选线、防灾减灾总体设计。灾害识别是减灾选线的基础;智慧选线是减灾选线的关键;做好铁路防灾减灾总体设计是减灾选线的根本目标。The route selection technology of railway in the mountain area has experienced three stages of development from"route selection according to topography","route selection according to geology"to"route selection for disaster reduction".Based on system engineering,the route selection for disaster reduction pays more attention to the engineering and operation safety of the railway in the whole life cycle and the identification,prevention and control of disaster risk affecting the safety of railway engineering and operation,and also puts more emphasis on risk aversion,prevention and control from the engineering design stage.The railway route selection techniques for disaster reduction include disaster identification,intelligent route selection and overall design of disaster prevention and reduction,in which the disaster identification is the basis,the intelligent route selection is the key and the good overall design of railway disaster prevention and reduction is the basic goal for the railway route selection techniques for disaster reduction.
