防波堤越浪次生波近滩面传播试验研究
Experimental study on the propagation of secondary waves across breakwaters near the beach
摘要
Abstract
In this paper,the cross-sectional physical model test with a geometric scale of 1∶38 was carried out to study the wave overtopping behind the Colombo New City breakwater and revetment,as well as the secondary wave height behind the breakwater.It can be obtained that the largest secondary wave height appears near the back of the breakwater.When the secondary waves induced by the overtopping propagate to the shore,the wave height attenuates with the amplitude up to 62％.When the waves reach to the nearshore zone,the wave height increases again due to the shallow water deformation with the amplitude up to 36％,which is much smaller than the increasing amplitude.When the wave propagates further to the revetment,the wave height decreases rapidly due to the energy loss by wave breaking.In order to reduce the damage of the secondary waves to the wave-proof structures,the distance between the breakwater and the structures behind should be reasonably set to reduce the secondary wave energy as much as possible.关键词
