长江河口江面开阔,口门宽度约90公里,口外又无岛屿屏障,每秒8米的风速,口门地区可掀起波高为1米左右的风浪,夏秋季节如遇台风影响,浪高更为可观.波浪作用不仅是河口河槽演变不可忽视的因素,而且对河道整治、港口建设、护岸保坍、促淤围垦等工程设施有深刻的影响.本文以引水船和高桥两站的资料为基础,论述长江口风浪的基本特性及其对岸滩的作用,并提出风浪要素的经验关系,为长江河口治理提供依据.文中提出的风浪要素计算方法,也可供缺乏波浪资料的潮汐河口地区参考和应用.
The river mouth of the Yangtze River is open with a width of about 90 km. There is no island barrier in the mouth and no windshield of 8 meters per second. The wind and waves with a wave height of about 1 meter can be raised in the gate area. In summer and autumn, when the typhoon is affected, the wave height is even more impressive The wave action is not only the factor that can not be neglected in the evolution of river mouth fluvial, but also has a profound impact on engineering facilities such as river regulation, port construction, bank protection slump, siltation reclamation, etc. Based on the data of water diversion vessel and Takahashi Station, Discusses the basic characteristics of the storms in the Yangtze River estuary and their effects on the beach, and puts forward the empirical relationship between the elements of the storms and provides the basis for the management of the Yangtze estuary. The calculation method of storms and waves proposed in this paper can also be used for the reference and application of the tidal estuary lacking the waves .
