| 摘 要： | 本文从床面附近泥沙颗粒的运动特征出发,详细分析波浪作用下床面泥沙扬起的动力学机制,得到了波浪掀沙计算公式,计算结果与实测资料相吻合。研究表明淤泥质海岸泥沙颗粒的稳定性主要受制于颗粒间的粘结力和薄膜水压力,重力作用则居于次要地位,因此泥沙颗粒越细越难以起悬。

| Abstract: | In this paper, a systematic study on dynamic mechanism of sediment particles being winnowed from seaded by wave action is carried out. An equation for sediment winnowing caused by wave is established. The calculated results are in good agreement with the measured data in the Yellow River estuary. |
