针对挡潮闸闸上河床演变的响应研究较少的问题,以浙江省强潮河口曹娥江口门建闸为例,基于建闸前水沙输移特点及河床演变分析,采用动床数学模型研究了建闸对闸上河床演变的影响。结果表明,建闸后闸上河道蓄水及口门侵蚀基面抬高,闸前至新三江闸河段内呈壅水淤积,新三江闸以上河段发生单向冲刷。 Based on the analysis of the characteristics of sediment transport and sediment transport in front of the sluice gate in Cao’e River Estuary of Qiangchao River estuary in Zhejiang Province, the dynamic response model of dynamic bed model The effect of sluice gate on the evolution of sluice bed was studied. The results show that after the sluice, the impoundment of the river waterway and mouth gully is raised. The water from the gate to the Sanjianjiang River reaches sediment deposition, and one-way scouring occurs above the Sanjianjiang River.
