曹妃甸建港前后深槽稳定性及冲淤原因分析

Analysis of stability and reason of erosion and siltation of deep groove before and after caofeidian construction

从2003年曹妃甸深水大港建设拉开序幕开始,至今曹妃甸建设已经经过了14个年头,从当时广阔的潮滩变成了今日以人工岛为主体、以板块结构和港池相间为特征的大港。本文利用多年的地形监测资料对曹妃甸港口建设前后深槽地形变化情况及冲淤原因进行了分析,为港口发展提供了科学依据。

Since the beginning of the construction of Caofeidian deepwater port in 2003,the construction of Caofeidian has gone through 14 years,from the vast tidal flat at that time,it turned into a large port with artificial islands,the plate structure and the basins as the main body today.In this paper,topographic changes and the cause of erosion and siltation in deep grooves before and after the construction of the Caofeidian port were analyzed by using the landform monitoring data,which provides a scientific basis for the development of the port.
