摘要

摘要: 波浪是导致沉积物再悬浮发生的主要动力条件之一,通过室内水槽试验利用浊度剖面仪(Argus Surface Meter IV,简称ASM-IV)研究15 cm恒定波高的波浪持续作用下沉积物再悬浮的发生过程,试验过程中确立了黄河三角洲地区水体悬沙浓度与ASM-IV所测浊度之间的相关关系,研究了波致海床沉积物再悬浮的发生发展过程,分析计算波致沉积物再悬浮泥沙总量及其通量随时间和空间的变化规律,定量地计算出本次试验中波致悬浮泥沙总量以及液化所导致沉积物再悬浮量及其所占比例。研究发现,波致液化作用是沉积物再悬浮的主要动因,液化悬沙量占总悬沙量的76.4%,本试验对进一步探讨波浪作用下海床沉积物再悬浮过程具有一定的参考意义。

Abstract: Wave is the main factor to initiate sediment resuspension. In this paper, we presented a case of wave-induced sediment re-suspension under the wave of 15cm in height. The equipment of ASM-IV is used to establish the correlation between the suspended sediment concentration and the turbidity measured by ASM-IV. In this article, we quantitatively calculated the total amount of suspended sediment induced by waves, and the part caused by liquefaction as well as their proportion to the total amount. Results indicate that liquefaction induced by waves is the main cause of sediment re-suspension, which accounts for 76.4% of the total. The work provides an important reference to the further study of the wave induced re-suspension.
