Engineering Measures for Preventing Upheaval Buckling of Buried Submarine Pipelines

  • 摘要: 为减小油气输送难度和避免原油固化,石油、天然气通常在高温高压下输送.输送过程中的高温和高压导致海底管线中产生较大的附加应力,附加应力的不断累积造成管线发生整体屈曲.对于埋地的海底管线通常会产生竖向屈曲大变形而影响使用甚至破坏.因此,需对有可能产生整体屈曲的管线采取工程防护措施.结合我国海洋工程中管线常用的铺设及保护措施,对处于保护状态下管线由温度应力引起的整体屈曲特性进行理论分析和数值推导,对沟槽保护、沟槽掩埋保护以及压块保护措施的有效性进行了系统分析和对比.
