【摘要】 浮泥发育水域水体的含沙量通常变幅较大,无法与水流流速建立良好关系.在分析浮泥水域含沙量时空变化特征及常用挟沙力公式的基础上,提出了以浮泥重度为参数的挟沙力公式.该公式建立了浮泥水域水体含沙量与浮泥床面泥沙条件的关系,使泥沙数学模型中泥沙输运过程的数值模拟结果更加符合实际情况,有助于提高泥沙数值模拟精度.更多还原

【Abstract】 The sediment concentration of suspended load always varies in large scale and its relationship with the current velocity in fluid mud area can not be well established.A formula of sediment-carrying capacity based on fluid mud density is recommended for numerical model of sediment.The formula combines the suspended load with bed sediment conditions well in fluid mud area.It is possible to insure sediment transport process according to natural phenomenon and increase the accuracy of sediment simulation in the numerical model by this way.更多还原
