摘　　要：亚吉铁路起于亚的斯亚贝巴,止于吉布提港,沿线自然环境多样,部分铁路走行于戈壁滩上,后期运营中产生了不同程度沙埋现象,是典型的风沙地区路基。为此,通过搜集当地气象、风向与风速资料分析当地的风沙等级,在此基础上提出有效、可行的治理措施,效果良好。Addis Ababa-Djibouti Railway starts at Addis Ababa and ends at Djibouti ports,with varieties of natural environment along the line,wherein some sections pass through gobi desert,leading to inordinate sand burial in the later operation,i.e.typical subgrade in sandy area.Therefore,the local data of weather,wind direction and speed were collected to analyze the local sand-wind grade,and based on these information,the effective and feasible control measures were proposed,and got good effect.
