The double-deck monomer floating structure under the rules of two-dimensional wave action for the study of physical model experimental, measuring the wave height behind the structure in the experiment, calculated the transmission coefficient. Based on considering the different water depth, the different ways of putting, the different row numbers, the different materials and with or without net cage to analysis the condition of wave dissipation effect. Water depth in 0.5 m, the model above the water of 0.06 m; Water depth in 0.6 m, the model covered 0.04 m and the periods were ranging from 0.8 to 1.1 seconds.
Since the 1950s, China's coastal erosion is more and more obvious and damage continues to intensify. Such as The DiaoKou River spit in the Yellow River delta from 1976 to 1986 was eroded about 6 km, erosion area was of 100 km(2). From1986 to2002, the corrosion is gone around 1 km, the corrosion area is around 37 km(2). one of the important reason about erosion is the impact of ocean waves(). the impact of the wave caused a loss in China Fisheries and Aquaculture, seriously affected the social economic development and people's living standards. Therefore, the study of coastal zone protection measures, reduce the impact on the deep water aquaculture area of ocean waves is an urgent issue.
Generally measures to prevent coastal erosion mainly include two categories: one is the hard environment, resist the coastline back or cut along the wave energy, such as building breakwater wall, dike, jetty, submerged breakwater, the offshore breakwater etc; second, the soft environment, adopt the methods for simulating the characteristics of coastal systems against coastal erosion, such as filling sand to protect beach, building shelter belt, biological revetment measures. These measures were large Construction, very difficult, working too long, expensive, complex structure and not suitable for deep water aquaculture area, so some floating wave device movement is born, they are construction of small, simple, time short, low cost, light weight and so on relative to the former. In addition, they also do not destroy the waters of the integrity and ecological environment.
There are many floating wave structure type([3-8]), in this paper, it study on a kind of double monomer floating wave structure, especially suitable for the deep waters(), waves through the model To achieve wave dissipation effect. Through the permeability coefficient to comparative and analysis of wave dissipation effect, then provide reference for practical engineering applications.
