| 摘 要： | 汊道封堵是洋山港建设的规划方案之一,是后续码头建设的基础工程,其实施也是对港区水动力变化和海床冲淤演变产生影响的主要工程。迄今为止,港区北部颗珠山-小洋山汊道和南部双连山-大山塘汊道及大山塘-大洋山汊道保持畅通。这几个汊道是否封堵一度成为热点问题。本文通过通量分析方法,分析汊道位置水沙输运年际变化。结果表明,颗珠山汊道单宽净输沙通量逐年增强,保留颗珠山汊道是必要的。

| Abstract: | Inlet closure is one of the layouts of the Yangshan Harbor Project,the fundamental engineering for port building,and its completion is a primary contribution to hydrodynamic and sea bed accretion/erosion change.So far,the inlets between Kezhushan Island and Xiaoyangshan Island in north,between Shuanglianshan Island and Dashantang Island and between Dashantang Island and Dayangshan Island in south remain open.Whether closing these inlets has ever been a hot issue.The paper analyses the yearly variation of water and suspended sediment transport based on flux analysis.The result shows that it is essential to remain the inlet between Kezhushan Island and Xiaoyangshan Island open because the net suspended sediment transport out of the harbor per unit width in normal direction increases with year. |
