| 摘 要： | 以连云港进港航道为例,应用波浪、潮流共同作用下的二维泥沙数学模型,研究淤泥质海岸的泥沙运动及航道回淤问题。鉴于进港航道回淤量是当地海域潮流、波浪、泥沙长期共同作用的结果,建议采用年平均含沙量场进行回淤计算,并在此基础上模拟了连云港7万吨级进港航道的年回淤强度,计算结果与实测资料吻合较好。研究结果表明,所介绍的研究方法可以合理地描述含沙量场特性以及计算进港航道回淤量。

| Abstract: | Considering the effects of both tides and waves,a 2-D numerical model was used to simulate the sedi-ment movement in Lianyungang Harbor,and a large scaled average sediment concentration field of Hai-zhou Bay was computed.On the basis of sediment concentration field,the annual back silting intensity on the approach channel of 70 000 DWT at Lianyungang Harbor was also simulated,and the calculated results was coincident with actual data.The result showed that the numerical model could satisfactorily reflect the sediment concentration field,and calculate the back silting intensity on the approach channel in Lianyungang Harbor. |

| Keywords: | numerical model sediment concentration field approach channel back silting intensity model verification |
