摘　　要：宁波港自然条件优越,是世界上最繁忙的港口之一。鉴于水沙边界条件改变和人类活动加剧等影响,镇海港区和北仑港区出现了一定程度的淤积,维护疏浚量较大。基于实测水下地形断面资料,分析了甬江口外水域、北仑港水域近年来的冲淤变化特征,并对其淤积原因进行了探讨。With favorable natural conditions,Ningbo Port is one of the busiest ports in the world. Due to the influence of sediment and water boundary condition changes and increasing human activities,a certain degree of sedimentation appeared in Zhenhai and Beilun port areas,which requiring a lot of maintenance and dredging. Based on the measured underwater topography section data,this paper analyzed the scouring and silting variation characteristics in the waters at Yongjiang River estuary,Beilun port,and the west side of mountain channel in recent years,and discussed the reasons of siltation.
