摘　　要：为探究南疆线是否满足动车组开行要求,通过实车试验的方法,发现南疆线既有防风设施部分区段不能保证动车组安全运行,需进行优化改造;在分析试验结果的基础上,对试验中出现大值点的地段进行详细现场勘查和影像记录,分析总结需优化改造的防风设施结构形式等信息,发现南疆线既有防风设施薄弱环节处于无挡风墙地段、桥梁挡风结构、土堤式挡风墙、过渡段等位置。通过数值模拟计算,对土堤式挡风墙、浅路堑和土堤式下坡风等提出具体改造思路和优化方案。通过推荐施工方案、开展现场验证,以达到满足动车组安全运行的目的。The purpose of this study is to verify the feasibility of running EMU on Nanjiang Railway. It is found that the existing wind break facilities on some sections cannot guarantee the safety of EMU operation after a real train test was conducted on the railway. Based on the test result analysis, we made field survey and photologging for the sections tested with maximum value points and concluded such information as wind break structure for the to-be-upgraded sections which were mainly the locations without wind break wall, or with bridge wind break structure, earth embankment wind break wall or for transitional sections. Via numerical simulation, specific upgrading and optimization plans were proposed for earth embankment wind break wall, shallow cutting and earth embankment fall wind sections. And construction plans were recommended and site validations should be conducted to fulfill the requirements of EMU operation on Nanjiang Railway.
