摘　　要：管道设计是施工质量的基础,管道设计的合理性直接关系到管道的结构安全。为了保证管道设计的合理性,确保管道在各种工况下都能够安全运营,应用CAESARⅡ软件,建立埋地管道模型,对埋地管道进行应力分析。将分析结果进行模拟,得出结论:无论何种工况下,弯管都是应力危险的关键点;不同工况的应力影响因素不同。通过应力分析,可以为管道全线提供应力分析报告,从应力方面证明管道设计的安全性和科学性。Pipeline design is the base of the construction quality. The rationality of the pipeline design is related directly to the structural safety of a pipeline. In order to meet the rational requirements of pipeline design and ensure the pipeline＇s safe oper- ation under different conditions, the paper uses CAESAR II software to build a buried pipe model and carry out the stress analyti- cal. To simulate the analytical results, it gets the following conclusions ： Whatever the conditions are, pipe bends are always the stress dangerous point, and different working conditions have different influence factors. Through the static analysis, it provides stress analysis reports on the whole pipeline and prove the security and scientific property of the pipeline design.
