摘要:: 油气输送管道大部分为埋地管道，其应力分析与工艺管道不同，关键在于准确模拟管道与土壤的相互作用。结合国际上广泛运用的CAESARII 和AUTOPIPE 软件设计思路，阐述了埋地管道应力分析模型中对埋地管道离散化的理论基础和方法，模拟土壤与管道相互作用的原理以及相关数据的计算方法；对比分析了ASMEB31.4、ASMEB31.8 及国内相关油气输送管道设计规范对管道应力的校核要求；结合工程实例深化了埋地管道应力分析方法，对于开展管道应力分析工作具有积极作用，有利于增进对于管道应力分析及管道应力安全问题的认识。

Abstract:: Most oil and gas pipelines are buried pipelines, and their stress analysis, different to the process pipelines, mainly depends on the correct simulation of interaction between pipeline and soil. In combination with the world’s widely-used design ideas, CAESARII and AUTOPIPE software, this paper explains the theoretical basis and method of discretization for buried pipeline in the stress analysis model of buried pipeline, simulates the theory of interaction between soil and pipeline and the calculation method of related data; analyzes the verification requirements to pipeline stress in ASMEB31.4, ASMEB31.8, and related design codes in China regarding oil and gas pipelines; and deepens the stress analysis method of buried pipeline in combination with engineering examples, so it will be able to play an active role in pipeline stress analysis work and help to improve understanding of pipeline stress analysis and pipeline stress safety issues.
