摘要:: 高钢级油气管道环焊缝的断裂失效是目前中国油气管道工业最为关心的问题。近年来管道环焊缝断裂失效事故表明，导致环焊缝断裂的最主要原因是地质灾害引起的作用在管道上的土壤位移载荷。为保证管道安全，需要对土壤位移作用下含缺陷管道环焊缝进行完整性评价。在此，集成中国石油大学（北京）油气储运设施安全团队近十年来在地质灾害段管土相互作用、环焊缝失效机理与适用性评价方面的工作，介绍土壤位移与管道环焊缝裂纹断裂关联关系的建立及对含缺陷管道环焊缝进行适用性实时评价的系统方法，并就其中相关的具体环节所涉及的理论和方法进行了讨论。

Abstract:: Fracture failure of girth weld of oil and gas pipelines has become a key safety problem faced by the china pipeline industry. Recently, several girth weld failure accident occurred proved that the main fracture reason of girth weld fracture is the ground movement load induced by geological hazards. To insure the pipeline’s safety, it is necessary to perform integrity assessment on defected girth welds subjected to ground movement load. In this study, the research achievements about pipe soil interaction relationships of pipes located in geohazard regions, failure mechanism and fitness for service method derived by the oil & gas facility safety group from China University of Petroleum-Beijing in the recent decade was integrated. How to find a quantitative relationship between ground movement and girth weld fracture and furtherly carry out real time fitness for service assessment on defected girth welds were introduced systematically. The relevant basic theory and methods in this analysis were also elucidated or discussed.
