波浪和潮流共同作用下的输沙问题

Sediment Transport under the Joint Action of Wave and Tide

基于紊流中的泥沙受紊动支撑才得以悬浮的基本认识,从能量平衡原理出发,导出了潮流、波浪以及波、流共同作用下的悬移质挟沙能力及输沙率公式.野外和室内资料验证表明了公式的合理性,进而表明了公式所依据的基本理论的普适性。

Based on the mechanism that sediment is suspended by turbulent flow, formulas of carrying capacity and transport rate of suspended load under the action of tide, wave and their joint action are obtained from the principle of energy conservation. From verifcation with the observed data and the test data, it's shown that the formulas are rational and the fundamental principle is general compatible.
