摘要:: 在总结不同时期输油气管道抗震规范特点的基础上,分析了现役输油气管道抗震韧性评价影响因素,确定抗震设计、钢管腐蚀、地质灾害防治、应急处置4项抗震韧性评价指标,采用改进的KENT危险指数分析法,提出适用于现役输油气管道穿越活动断层地段的抗震韧性评价流程和方法,并应用于典型案例分析。初步验证了所提方法的科学合理性,为输油管道的地震风险治理提供参考。

Abstract:: On the basis of summarizing the characteristics of seismic design specifications for pipelines in different periods,this paper analyzes the influencing factors of earthquake resilience evaluation for oil and gas pipelines in service.Four evaluation indexes of earthquake resilience,such as seismic design,corrosion of steel pipe,prevention and treatment of geological disaster and emergency treatment are determined through improving the Kent Hazard Index analysis method,the flow and method of seismic resilience evaluation for oil and gas pipelines in service crossing active fault are proposed,and the typical case analysis is carried out.It preliminarily verifies the scientific rationality of the proposed method,it provides a reference for seismic rick management of oil and gas pipeline.
