摘要/Abstract

摘要： 采用大开挖直埋方式穿越河流的输油气管道易产生与河床面不发生直接接触的悬空段。为确定管道悬跨安全长度判定条件,对悬跨管道产生损毁的原因进行阐述,并分别从振动、疲劳和屈服破坏等方面对悬跨管道的损毁机理进行分析,借助分析工具对悬跨管道进行绕流、振动、静力和疲劳分析。根据分析成果,提出了穿越河流管道悬跨安全长度的判定条件悬跨段不发生振动破坏、不发生疲劳破坏且不发生屈服破坏。最后,辅以实例进行计算,以供管道建设及防护参考。

Abstract: Suspended span of river-crossing pipeline for oil and gas transmission is defined as the pipe segment which does not contact with the riverbed. To determine the judgment criteria of suspended span’s safety length, the causes of suspended span damage are expounded. The damage mechanism are analyzed in terms of vibration, fatigue, and yield. The flow analysis, vibration analysis, static structural analysis and fatigue analysis for suspended pipeline are carried out by means of relevant analysis tools. On the basis of the above analysis, the critical lengths of suspended span in vibration, fatigue and yield conditions are obtained, and the judgment criteria for the safety length of suspended span is proposed. Some calculation examples are provided for reference for the construction and protection of river-crossing pipelines.

Key words: oil and gas pipelines, suspended span, water flow impact, safety length
