马鞍山郑蒲港码头港池水域回淤分析

Analysis of Siltation in the Harbor Pool of Zhengpu Port Wharf in Ma'anshan

马鞍山港郑蒲港区位于长江马鞍山河段江心洲汊道左汊左岸郑蒲圩段,港池回淤受长江下游河势变化影响较大。本文将以马鞍山郑蒲港码头为依托,对港池水域历时(2011年~2023年)水下地形测量成果进行分析,从平面、横断面两个方面分析港池水域冲淤变化情况,结果表明马鞍山河段上下游局部河势的变化、主流的右摆,引起牛屯河边滩头部冲刷、尾部淤积下延,是郑蒲港淤积主要原因,为今后同类型港池回淤分析及应急清淤工作提供参考。

The Zhengpu Port Area of Ma'anshan Port is located on the left bank of the left branch of the central island of the Ma'anshan section of the Yangtze River.The silting of the harbor pool is greatly affected by the changes in the downstream river pattern.This article will analyze the recent(2011-2023)underwater topographic survey resultsof the harbor pool waters based on the Ma'anshan Zhengpu Port Terminal.On the one hand,it analyzes the changes in erosion and deposition of the harbor pool waters from both the horizontal and cross-sectional perspectives.The results indicate thatchanges in local river patterns upstream and downstream of the Ma'anshan section,as well as the rightward shift of the main flow,have caused erosion at the head of Niu Tun River beach and deposition at the tail,which is the main cause of silting in Zhengpu Port.This provides a reference for future calculations and analysis of similar types of silting.
