摘要
在全球气候变化的背景下,近年来经常出现极端波浪造成海岸工程的破坏.为重现破坏过程,研究破坏机理,解释大风浪下泥沙的起动与运动,分析结构与地基在大浪作用下的耦合作用,需要大尺度的波浪水槽进行试验研究,以突破比尺效应的限制.新型水槽造波机是该水槽中重要的设备.通过分析我国波浪和工程特点,对比应用需求,得到造波机的主要设计参数.设计建设中的大比尺波浪试验水槽长450 m,宽5m,深8～12m,建成后将是世界上尺度规模最大和造波能力最强的波浪试验水槽,配套造波机的设计波高达到3.5m.
Under the background of global climate change, it often appears the destruction of coastal structures caused by extreme waves. It is necessary to use the large-scale wave flume to reappear the destruction process, research the breaking mechanism, explain the sediment starting and movement under wind waves and analyze the coupling effect of the structure and foundation under big wave actions. The large-scale wave flume could break through the limitation of the scale effect. The wave generator of new wave flume is the most important equipment. According to the analysis of wave characteristics and requirement of the application, we obtain the design parameters for the wave generator. The wave flume designed and being and 8 to 12 m deep. It will be the largest-scale wave flume with the design wave height would be 3.5 m. under construction is 450 m long, 5 m wide, strongest wave power in the world, and the
