摘　　要：以某铁路站台封闭工程为项目背景,采用国际通用有限元分析软件MIDAS对大跨度抽空网壳进行稳定性分析,通过分析表明,双层柱面网壳结构刚度大,稳定性好,适应于大跨度结构,同时为其他工程项目提供参考和借鉴。Taking a railroad platform closure project as the project background,MIDAS,an international general finite element analysis software,is used to analyze the stability of the large-span evacuated mesh shell,which shows through the analysis that the double-layer column surface mesh shell structure has high stiffness and good stability and is suitable for large-span structure,and also provides reference and reference for other engineering projects.

关 键 词：铁路站台 稳定性 柱面网壳
