河口海岸环境中的淤泥在风浪、潮流作用下的输移 ,对港口航道淤积和污染物扩散有重要影响 .通过研究淤泥的流变特性 ,提出了非线性粘弹性模型 ,建立了波流共同作用下底泥输移计算的理论方法 ,并考虑了波浪不规则特征的影响 ,其计算结果与水槽实验结果大致吻合 The transport of silt in estuarine and coastal environment under storm waves and tidal current has an important influence on siltation of silos and diffusion of pollutants in the estuary. By studying the rheological properties of silt, a nonlinear viscoelastic model is proposed and the interaction of wave flow is established Underlying sediment transport calculation of the theoretical methods, and taking into account the irregular wave characteristics, the results of the calculation and the sink test results roughly agree
