摘要
通过分析杭州湾试挖槽区泥沙特性、水动力条件，研究浮泥产生及消失的原因．分析计算表明浮泥的形成和消失与潮流底流速有关．当底流速小于临界淤积底流速时，浮泥开始形成；而当底流速大于临界冲刷底流速时，浮泥开始消失．在此基础上。
Analysing sediment characteristics、 hydrodynamic conditions of Hangzhou Bay trial dradged-trough,this paper studies the reason of fluid mud emerging and disappearing. The analysis and calculation shows that the formation and disappearance of fluid mud are connected with the bottom velocity of tide. If bottom velocity is lower than critical bottom velocity which causes deposition, fluid mud comes into emerging; If bottom velocity is higher than critical bottom velocity which causes scour,fluid mud begins to disappear. Based on above analysis. the paper calculates the amount of siltting up caused by a process of fluid mud.
