摘要:
海洋波流冲刷易引起海底管道悬空,从而导致管道疲劳或强度破坏,引发油气泄漏等海上重大污染事故。本文针对我国某高潮差、强急流海域海底管道面临的冲刷问题,提出了不同类型的冲刷抑制方法,并通过模型试验对不同比尺、管径、海床流速、海床冲刷深度进行了研究,分析比较了不同冲刷抑制措施的防护效果,结果表明人工草压块联排结构防护方案在缓流、促淤、在位稳性及经济性等方面表现最优,最后将该方案应用于某实际海底管道冲刷抑制防护工程中,验证了该方案的冲刷抑制效果。本文研究成果为海底管道冲刷抑制及悬空治理提供了重要技术支撑和参考。
Abstract:
he ocean wave and current erosion can easily cause the free span of submarine pipelines and result in the fatigue or strength damage of pipeline, leading to major marine pollution accidents such as oil and gas leakage. This paper proposes different types of erosion suppression methods in response to the serious erosion of submarine pipelines in a high-tidal range and strong current sea area in China. Different scales, pipe diameters, current velocities and sea bed scouring depths have been studied through model test, and the protection effects of various erosion suppression measures have been analyzed and compared. The results show that scheme of concrete mattress with artificial grass has the best performance in the aspects of current slowing down, siltation promotion, in-situ stability and economy, and finally this scheme is applied in the erosion suppression protection project of an actual submarine pipeline, which verifies the erosion suppression effect of this scheme. The results in this paper can provide important technical supports and references for erosion suppression and free span control of subsea pipelines.
