摘　　要：传统的桩基透空式防波堤在冰冻区实施存在较大困难,为适应工程建设与生态环境协调发展的要求,提出一种适用于冰冻区的斜挡浪板透空式防波堤,并通过物理模型试验研究了其在不规则波作用下的消浪效果及受力性能。结果表明:当存在较强越浪时,透射波高由越浪和透浪两部分叠加组成,随着水位的增加,透射系数逐渐减小。经过模型试验验证,斜挡浪板透空式防波堤消浪效果较好,且挡浪板结构受力均匀。It is difficult to implement the traditional pile foundation permeable breakwater in frozen areas.In order to meet the requirements of coordinated development of engineering construction and ecological environment,this paper proposes a kind of permeable breakwater of the inclined baffle for frozen areas and studies the wave absorbing effect and mechanical performance of the permeable breakwater under the action of irregular waves by physical model test.The results show that when there is a strong crossing wave,the transmission wave height consists of crossing waves and permeable waves,and the transmission coefficient decreases with the increase in water level.The model test proves that the permeable breakwater of the inclined baffle has an excellent wave absorbing effect,and the force of the baffle structure is uniform.
