| 摘要: |
| 采用潮汐水流物理模型试验和泥沙淤积计算，研究、预测了现状条件下和金塘水道南岸拟建码头实施后大榭岛西侧浅滩的淤长趋势。在“大流大沙”环境中，海岸码头建设使浅滩区的落潮流速和进入穿山水道落潮流量均减小，导致浅滩加速淤长。现状条件下浅滩仍会淤长，拟建码头实施后，浅滩淤长速率和幅度均大于现状。 |

| Influence of dock construction along the south shore of Jintang Channel on beach development |

| Abstract: |
| The deposition trend of the shoal in the west of Daxie Island at present and after the construction of the lock along the south shore of Jintang Channel is studied by running a tidal current physical model test and using a deposition calculation formula. The construction of the dock will reduce the ebb tide speed in the shoal reach and the discharge of ebb tide in Chuanshan Channel, so the deposition speed of the shoal will increase. The shoal will be further deposited under present conditions, and the deposition speed and amplitude will be greater after the construction of the lock. |
