摘要
大洋山周边水深条件优越，风浪掩护条件好，有建设深水码头和开辟深水航道的条件。本文分析了大洋山水域潮流、波浪和泥沙特征，对深水航道开辟后的泥沙回淤进行了初步估算，认为目前航道浅段开挖后的回淤主要是以悬沙为主，如对平均水深１２ｍ的浅段浚深至１５５ｍ时年回淤强度在１２ｍ左右，并且在航道淤积过程中出现浮泥的可能性较大；此外还比较了作为上海港未来深水航道的大洋山深水航道与杭州湾深水航道的通航条件。
AbstractThe surroundings of Dayangshan has advantegeous water depth condition and good wind & wave shielding conditions, which are suitable for construction deepwater wharf and opening deepwater channel Based on the analysis of the tide, wave and silt characteristics of Dayangshan water area and preliminary estimation of the siltation after opening of the deepwater channel, it is considered that the siltation after excavation at the shallow section is mainly suspended sand For example, when the shallow sections with an average depth of 12m is dredged to 155m, the annual siltation volume is 12 m or so, and the possibility of appearing fluid mud is great during siltation Moreover, the navigation conditions of Dayangshan deepwater channel which could be the future deepwater channel of Shanghai Port is compared with that of Hangzhou Bay deepwater channel
