宁波港码头水域近年冲淤变化及原因初步分析

摘要

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 .%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。
