摘　　要：浮泥广泛存在于河口、海岸、内河和水库中,是引起航道淤积、地形演变和环境污染的关键因素。针对浮泥的形成机制及观测方法,对固结机理、浮泥流变、触变特性和浮泥输运规律进行了总结和讨论;目前研究成果的表达形式和适用条件存在差异,难以在实际应用中普遍使用;在此基础上应重点关注浮泥内部结构和外部荷载及生物因素影响,及大型水库中浮泥特性和输运规律的系统研究。Fluid mud is extensively found in estuaries,coasts,inland rivers and reservoirs and it is a key factor to cause channel siltation,topographic evolution and environmental pollution.In response to the formation mechanism and observation method of fluid mud,the consolidation mechanism,rheological and thixotropic characteristics of fluid mud,as well as the transport laws of fluid mud,were summarized and discussed.However,the expression forms and application conditions of research results at present are different,which are difficult to be widely used in practical engineering.On this basis,the internal structure of fluid mud,external loads and the influence of biological factors,as well as the systematic study on characteristics and transport laws of fluid mud in large reservoirs should be focused.
