摘　　要：基于实测数据,分析了镇扬河段世业洲右汊历年来水来沙特点,研究了镇江港码头工程附近河道河床近年来的冲淤变化。结果表明,世业洲汊道河段多年来一直维持相对稳定的河势,河道深泓走向和滩槽位置相对稳定;镇江港码头位于世业洲右汊凹岸,近岸动力较强;多年来滩槽位置相对稳定,深泓线和深槽靠近右岸;虽然近几年右汊左岸边滩变化较大,但深槽位置较稳定,前沿水深一直保持在-13.0m左右,无需开挖即可满足船舶停靠的要求,-10m水深的河宽多年来一直稳定在600m以上,具有良好的水域条件。Based on the measured data,this paper analyzes the characteristics of water and sand in the past year of Zhenyang River,and focuses on the scouring and silting changes of river bed near Zhenjiang Port.The results show that the river channel has been maintained relatively stable for many years,and the river direction and the beach position are relatively stable.Zhenjiang Port is located in the world industry right bank depression,strong coastal power.Over the years the beach position is relatively stable,the thalweg and deep pool are near the right bank.Although the change of left bank of the right branch is greater in recent years,the position of deep pool is more stable,and the front edge of water depth has been maintained at-13.0 mor so,which can meet the requirements of the ship docking without excavation.River width with-10 m water depth is stable at 600 min over the years,which has good water area conditions.
