Experimental Investigation of Wave Transmission Coefficient for Permeable Tubular Breakwater
摘要
Abstract
A physical model test is adopted to investigate the wave dissipating performance of permeable tubular breakwater.Transmission coefficient Kt serves as key parameter to explore its relationship with breakwater top width B,slope m,tube diameter D and wave factors.The results show that the transmission coefficient Kt decreases with the increment of relative breakwater width B/L,wave steepness H/L and water depth h/L.When B/L exceeds 0.3,H/L exceeds 0.06,and h/L exceeds 0.3,the corresponding transmission coefficients obviously decrease and then gradually become stable,which shows significant wave dissipation effect.Kt increases with the increment of the slope m,and the breakwater has better wave dissipation performance subject to the slope of 1:1.5.Moreover,the combination of different tube diameters achieves better performance of wave dissipating than that of only one tube diameter.The permeable tubular structure is of better performance of wave dissipation than that of permeable horizontal-plate structure under same working condition.关键词
