摘　　要：为确保管道在安装、试压、运行条件下安全,管道项目均应进行应力分析,以满足管道设计强度和柔性要求。文中以某输气管道工程输气站场为例,通过边界条件的简化处理并考虑埋地段与土壤的真实效应,在CAESARⅡ中建立了输气管道站场应力分析模型进行应力校核、清管工况应力分析。在安装工况、试压工况、运行工况以及清管工况条件下,站场应力模型满足应力校核需求,分析方法和结果也可以做为类似分析的参考。In order to guarantee the safety of pipeline in the condition of installation, strength testing and operation, stress analysis of pipe should be conducted in piping project, which, therefore, meet the requirement of design strength and flexibility of pipeline, In the background of piping project, gas station piping model was built in CAESAR Ⅱ. By stress analysis, it was ob- tained that the gas station piping model meet the requirement of stress in the condition of installation, hydraulic press testing, op- eration and pigging. The method and result of analysis can provide a reference for similar analysis.
