海底管线作用下的泥沙休止角的试验研究

EXPERIMENTAL STUDY ON THE ANGLE OF REPOSE OF SEDIMENT UNDER THE ACTION OF SUBMARINE PIPELINE

由于海底水动力环境的复杂性,海底管线破坏等问题日益突出,而海床的冲刷是管线破坏的一个重要原因。本文经对单向恒定流作用下的海底管线冲刷坑内泥沙动水休止角这一特征参数的理论分析和试验研究,得到其相关关系和变化规律,对进一步研究海底管线的防护技术有一定参考价值。

Owing to the complexity of the dynamic environment of seabed, the problem has manifested itself in the destruction of submarine pipelines, and the erosion of sea bed is one of the reasons. After theoretical analysis and experimental study on the angle of repose of scour pit under the action of unidirectional flow in this work, the correlativity and variation law was found which has the reference value for further research inthe protective technology of submarine pipeline.
