针对淤泥质海岸泥沙运动形式和淤泥质海岸近岸缓坡地形的形成原因两个基本问题,通过对比分析浮泥与悬移质运动特征的差异,得到了“在泥沙沉积过程中,浮泥的整体性运动可表述为淤泥质海岸的推移运动”的结论;进而,建立浮泥平衡坡度理论模型并进行计算。研究表明:小容重浮泥的平衡坡度与淤泥质海岸实际坡度吻合较好,浮泥是淤泥质海岸近岸缓坡地形形成的重要因素之一。
In view of the two basic problems of the sediment movement form of the silt coast and the formation of the coastal gentle slope topography of the muddy coast, the difference between the movement characteristics of the mud and the suspended sediment is analyzed and compared. The results show that during the sediment deposition, The overall movement of mud can be expressed as the movement of muddy coast. "In addition, the theoretical model of floating mud equilibrium slope is established and calculated. The results show that the equilibrium slope of small volume heavy mud agrees well with the actual slope of muddy coast, and the floating mud is one of the important factors for the formation of gentle slope terrain of muddy coast.
