贯顶式沉箱堤坝消浪减流特性的试验研究
Experimental Study on Wave and Flow Reduction Characteristics of Perforated Caisson Dike
摘要
Abstract
Aiming at the problem of increasing port erosion under the background of global warming,in order to improve the protection effect of dikes on ports,a new type of perforated caisson dike is pro-posed in this paper.The reflection coefficient,transmission coefficientand the maximum flow velocity in front and behind the dike are analyzed by the indoor wave flume test of the new type of perforated cai-sson dike and the traditional rectangular caisson dike under different incident wave conditions and differ-ent water depth of the dike.The test results show that the new perforated caisson dike has stronger wave energy dissipation capacity than the traditional rectangular caisson dike when used in non-large dike top water depth.Compared with the rectangular caisson dike,the transmitted wave height can be reduced by 5.5%～32.2%,the reflected wave height can be reduced by 3%～37.9%,and the maxi-mum velocity in front of the dike can be reduced by 6.3%～19%.The maximum velocity behind the levee can be reduced by 4%～52.2%.On the whole,it shows excellent performance of reducing wave reflection and reducing current.关键词
