摘　　要：风沙危害是影响沙区铁路建设运营的主要因素,风沙铁路减灾选线及防护工程科学设计能有效地减少线路风沙灾害。为进一步丰富完善风沙地区铁路选线与防沙工程设计的理论方法,通过分析风沙地区的地理环境属性和铁路沙害特征,将风沙区域划分为流沙环境、戈壁大风环境和高寒风沙环境;研究不同环境下选线设计的控制因素,基于灾害学理论和综合选线方法,提出了各环境中减灾选线及防沙工程设计的基本原则。以风沙地区和若铁路、格库铁路和青藏铁路为例,通过系统分析风沙危害、环境影响和工程投资等,实现了线路减灾选线设计,并根据铁路沙害防治要求给出了不同地区风沙防护工程的基本设置模式,可为今后风沙铁路减灾选线及防沙工程设计提供一定的指导和参考。Wind-sand disaster is the main factor affecting railway construction and operation in sandstorm area,sandstorm damages to the railway could be effectively reduced by implementing route selection for disaster reduction and designing scientific protection engineering.In order to further improve the theoretical method of railway route selection and the design of sand control engineering in sandstorm area,sandstorm areas are classified into quicksand region,Gobi gale area and plateau cold region based on the characteristics of geographical environment and sandstorm damages to the railway in sandstorm areas.The control factors of route selection design in different environments are studied.Based on the disaster theory and comprehensive route selection method,the basic design principles of route selection for disaster reduction and sand control engineering in each environment are put forward.With reference to the Hotan-Ruoqiang Railway,Golmud-Korla Railway and Qinghai-Tibet Railway in sandstorm area,the route selection design for disaster reduction is realized by comprehensively analyzing the wind-sand disaster,environmental impact and engineering investment.According to the prevention and control requirements of sandstorm damages to the railway,the basic modes of sand protection engineering in different areas are given.The research results can provide some guidance and reference to route selection for disaster reduction and sand control engineering design of railway in sandstorm area.
