【摘要】：为了解影响舟山岛的台风浪特性,基于舟山岛东北部沿海水域深、浅水两个测站同步测量的6个台风过程波浪资料,统计分析了两测站的波参数变化和谱变化特性,探讨了波浪变化的原因。研究显示:1灿鸿过程的深、浅水站最大波高均大于其他5个台风浪过程;2多数台风浪过程深水站波向主要为东及东南东向,而浅水站主要为东、东北东及东北向,水下地形对波向变化起主要作用;3不同路径台风对两测站谱型有明显影响,灿鸿、巴蓬、黄蜂和天鹅过程的波浪在两站以双峰谱为主,苏迪罗和杜鹃过程深水站波浪以单峰谱居多,浅水站则多峰谱多于单峰谱。研究成果对沿海建筑物的设计以及防灾减灾有重要参考价值。
[Abstract]:In order to understand the characteristics of typhoon waves in Zhoushan Island, six typhoon wave data were measured synchronously by two shallow water stations in the northeast coastal waters of Zhoushan Island. The variation characteristics of wave parameters and spectra of the two stations are statistically analyzed and the causes of wave variation are discussed. The results show that the maximum wave height of the shallow water station is higher than that of the other five typhoon wave processes. (2) in most typhoon wave processes, the wave directions of deep water stations are mainly east and southeast, while shallow water stations are mainly east, northeast and northeast, and the underwater topography plays a major role in the wave direction change; (3) Typhoon with different paths has obvious influence on the spectral patterns of the two stations. The waves of the processes of Chan-hung, Bafeng, wasp and swan are mainly bimodal in the two stations, and the waves in the deep water stations of Sudiro and Rhododendron process are mostly single-peak. The multi-peak spectrum of shallow water station is more than that of single peak spectrum. The research results have important reference value for the design of coastal buildings and disaster prevention and mitigation.

【正文快照】： 台风对浙江沿海影响显著,主要在每年5月至11月出现,8月出现最多[1],其引起的波浪常常对港口、海堤等沿海建筑物产生重大破坏,对人民生命财产安全造成严重危害。舟山岛位于杭州湾外舟山群岛南部,受台风浪影响严重。2015年第9号超强台风“灿鸿”于7月11日以强台风级别在舟山登陆
