摘要
港口航道的泥沙骤淤特征对海港建设及运营管理具有重要意义。通过分析台州市头门港区进港航道试挖槽回淤监测的基础数据,研究开敞海域航道开挖后的回淤过程特征。结果表明:台风期间试挖槽被浮泥淤平;台风后5个月,试挖槽内浮泥逐渐压实、槽内高程逐渐下降。台风作用下高含沙量水体是港区航道淤积的主要原因。
The characteristics of sudden sediment deposition in the port channel are of great significance to the construction and operation management of the port.In this paper,based on the analysis of the basic data of the siltation monitoring of the trial excavation channel of Toumen port in Taizhou,the characteristics of the siltation and erosion of the open sea channel are studied.The results show that the trial trench is silted by floating mud during typhoon period,and the floating mud in the trial trench is gradually compacted and the elevation in the trench is gradually decreased within a few months after typhoon;The siltation of Toumen port channel is mainly caused by the high sediment concentration water body under the action of typhoon.The scouring and silting characteristics and silting formation conditions of Toumen port channel can provide reference for the research and prediction of scouring and silting of other muddy harbors.
