摘　　要：对兰铁局辖区60多年干旱沙区风沙危害铁路治理模式进行总结,为干旱区铁路沙害防治提供技术方案。在灌溉条件下,建立的以乔灌木为主体铁路沙害防护体系,一级沙害区;在无灌溉条件下,建立工程固沙+植物固沙雨养型铁路沙害防护体系,适合年降雨量160 mm以上沙害地区,二级沙害区;在无灌溉条件下,建立工程固沙铁路沙害防护体系,适合年降雨量160 mm以下的沙害地区,三级沙害区;“高立式沙障+格状沙障”适合一级沙害地区;“高立式沙障+积沙沟”适合二级沙害地区、“格状沙障”适合三级沙害地区。This paper summarizes the railway sand hazard control models in arid sandy areas under the jurisdiction of the Lanzhou Railway Bureau over the past 60 years,providing technical solutions for the prevention and control of sand hazards in arid railway areas.Under irrigation conditions,a railway sand hazard protection system dominated by trees and shrubs can be established,suitable for primary sand hazard areas.Under non-irrigation conditions,an engineering sand fixation plus vegetation sand fixation rain-fed railway sand hazard protection system can be established,suitable for sand hazard areas with annual precipitation of more than 160 mm,categorized as secondary sand hazard areas.Under non-irrigation conditions,an engineering sand fixation railway sand hazard protection system can be established,suitable for sand hazard areas with annual precipitation of less than 160 mm,categorized as tertiary sand hazard areas."High-standing sand barriers+grid-shaped sand barriers"are suitable for primary sand hazard areas;"High-standing sand barriers+sand accumulation ditches"are suitable for secondary sand hazard areas;"Grid-shaped sand barriers"are suitable for tertiary sand hazard areas.
