摘　　要：文中对沙波区海底管道的冲刷进行了研究,包括海底管道冲刷下降和掩埋的机理,海底管道冲刷的开始和发展,固定管道和下降管道的平衡冲刷深度,冲刷达到平衡深度的时间预测以及跨肩承载失效导致的管道下降。结合工程实例进行了计算分析并得出结论,为沙波区的海底管道工程设计提供参考。The scour of submarine pipeline in sand wave area was studied, including the mechanism of scour falling and burying, the beginning and development of submarine pipeline scour, the equilibrium scour depth of fixed pipeline and sagging pipeline, the time prediction of scour reaching the equilibrium depth and the pipeline falling due to cross-shoulder bearing failure. Combined with engineering examples, the calculation and analysis are carried out and the conclusion is drawn, which provides a reference for submarine pipeline engineering design in sand wave area.
