波浪作用下的底泥质量输移

MASS TRANSPORT IN THE MUD BED DUE TO WAVES

基于天津新港淤泥的实测流变数据提出了一种简化的非线性流变关系，并建立了波浪与淤泥质底床相互作用的多层模型，讨论了规则波和不规则波作用下的底泥质量输移．结果表明，理论计算与实验测量得到的底泥质量输移速度剖面有较好的一致性．

A simplified nonlinear rheological relation is presented in this paper based on the measured rheological data of mud deposited in Tianjin New Port. A multi layer hydrodynamical model is developed and mud mass transport due to regular and irregular waves is discussed. The profiles of mass transport velocity obtained by the theoretical model and the measured by the experiments show good agreement.
