Experimental Study On Wave-eliminating Characteristics Of Semi-submersible Used Tires

With the development of ocean engineering gradually to the deep,the traditional structure form wave application is limited by a certain structure,advantage of the new wave structures appeared gradually.In recent years,the use of the new wave structure has aroused people's more and more attention,because it does not destroy the waters of the integrity and ecological environment,not change the flow and sediment movementThe characteristics of the condition,especially suitable for need to wave the deep waters.Along with our country economy fast development,the car number increasing,the recycling of waste tyre problem more and more serious,considering the tyre is durable,green environmental protection,so for a semi-submersible structure composed of waste tire new wave structures of can yet be regarded as a kind of advanced study.In ocean wave structures of scrap tire as the main material of the structure of the semi-submersible applied research are less common,so in order to understand the semi-submersible wave characteristic of waste tyre structure,master,the factors which influence the wave effect on relative width,the relative water depth and relative level spacing,vertical net net spacing,arrangement,and the effects of factors such as the cancellation in the wave on the physical model test,and understand the rules on the wave properties of semi-submersible structure,the test results show that the transmission coefficient in relative width decreases with the increase of the width is greater than 0.6,decreases with increasing the depth of water,the influence law of horizontal spacing is not very obvious,when the model into the water,monolayer horizontal wave steepness H/L and relative wave height H/d's influence on the transmission coefficient is not very big,and double level cases,change the wave steepness H/L and relative wave height H/d's influence on the transmission coefficient is very obvious,for single level case width B = 2.52 m in the draft depth wave effect when q = 0.03 m,vertically than horizontal arrangement best wave,etc.For wave,because the model into the water below the surface,can make the water surface and the following section broken waves,waves destroyed the original movement,can also be reflected wave attenuation of wave to achieve.With the existing various floating and semi-submersible wave structures compared to economic,reliable,and easy in materials.Key is wave structure is to infiltrate below sea level can be in does not affect the whole tourist attractions beach effect can be achieved at the same time very good wave effect,for it can be widely used to provide important basis.For coastal zone protection,reducing the waves on the beach erosion plays an important role.
