台州湾近海海域波浪要素特征分析

波浪要素的观测及分析对港口码头设计、航道建设、围垦工程等都尤为重要。为研究台州东部新区临时航道疏浚工程对周边涉水工程的影响,采用SZF型波浪浮标,在工程海域进行为期一年的波浪观测,并对实测的波浪要素进行统计分析。结果表明:台州湾全年以东北向波浪居多,东向浪最大,可高达5 m。波高主要集中在0.5 m~1.0 m范围,波周期集中在3.0 s~4.0 s范围。春季浪向分散,夏季浪向集中在S向,秋冬季浪向相似,N为主波向。受台风影响,夏秋季有大浪出现。

Wave Characteristics in Coastal Area of Taizhou Bay

Wave observation and data analysis are very important to the design of harbour,channel or other engineering projects.In order to study the influence of the temporary channel on the surrounding engineering projects which are associated with water in the new eastern area of Taizhou,the one-year wave observation project was conducted using the SZF wave buoy.The obtained data was analyzed and the results show that:the main wave is in the north-east direction while the highest wave which can reach 5 meters is in the east direction.The wave height mainly focus on the range of 0.5 ～1 meters while the wave period is mainly between 3.0 s ～ 4.0 s.Wave direction is dispersed in spring while mainly focused in S direction in summer.The distribution of wave direction in fall and winter is similar and they both take N as the main wave direction.Also,they both have strong wave due to the typhoon impacts.
