摘要
在对管道凹陷进行分类的基础上,综述了不同类型凹陷静压爆破强度和疲劳强度的研究现状。介绍了凹陷的回弹机理、回弹量的计算方法以及外载与凹陷深度的关系等方面的研究成果。对开展管道凹陷的力学行为、形成机理、评估方法等方面的研究提出了建议。
Based on classification of pipelines with dents,the paper reviews research actuality of burst strength and fatigue strength of various dents,discusses research results of mechanism and calculation method of rerounding about dents and relationship between external load and depth of dents.At the same time,the paper makes suggestions that further research should be conducted on mechanical behavior,formation mechanism and evaluation method of the pipelines with dents.
