摘要
对铜鼓浅滩泥沙的起动、运移形态进行了试验研究。结果表明 :铜鼓浅滩泥沙具有典型的淤泥质泥沙的运移特征。当水流单独作用时 ,该地泥沙很难起动 ,而在波浪或波、流共同作用下 ,该地泥沙一旦起动 ,即“悬扬”后将以悬移质形态运移。根据其流变特性和矿物成分 。
Test studies on starting and transport pattern of sediment of Tonggu Shallows were performed.The results show that sediment of Tonggu sallows have typical characteristics of the transport of muddy sediment.When current exists alone,it is difficult for sediment to start.However,under the effect of wave or wave current coexisted,once sediment is mobilized,'lifting suspension' will transport as suspended load.Finally,according to the rheological property and mineral constituent,the causes of sediment hardly starting were analyzed.
