温州浅滩围涂工程对港口航道的影响研究

采用波浪、潮流、泥沙数学模型,对瓯江口温州浅滩围涂工程海区的工程前后的波浪场、潮流场、悬沙场、底床冲淤进行了数值模拟研究,对温州浅滩围涂工程对瓯江口港口航道的影响进行了分析论证。研究结果表明,温州浅滩围涂工程不仅对温州港现有港口航道及未来的状元岙深水港区基本没有负面影响,而且有利于航道水深的维护和稳定,可以改善从瓯江北口到黄大岙水道的船舶航行条件。

Study on the Influence of the Reclamation of the Wenzhou Shoal on Wenzhou Harbour and Its Navigational Channel

By means of mathematical models of wave,tidal flow and sediment,numerical simulations are carried out on the wave field,tidal flow field,suspended sediment field and seabed erosion and siltation at Oujiang estuary before and after the reclamation of the Wenzhou shoal.According to the numerical simulation results,the influence of the reclamation of the Wenzhou Shoal on Wenzhou harbor and its Navigational Channel at Oujiang estuary is analyzed and justified.The study results show that the reclamation of the Wenzhou shoal not only has little negative influence on the existing harbour and navigational channel and the future Zhuang Yuan'ao deepwater harbor,but also is favourable to the maintenance and stability of the navigational channel and improve the navigation conditions from the north branch of Oujiang estuary to Huang da'ao waterway.
