摘要
Abstract
Based on the potential flow theory,the linear wave hypothesis and the method of matched eigenfunc⁃tion expansions were applied to solve the diffraction and radiation problems of the floating box⁃type breakwater. In the region II,eigenfunction expansions were in the form of the division of two hyperbolic sine(cosine)functions, which were conducive to the numerical convergence. The effects of width,draft,height of gravity center and preten⁃sion on the transmission coefficient of the breakwater were studied. The results indicate that increasing the width and draft of the breakwater can reduce the transmission coefficient. The height of the gravity center has little influ⁃ence on the wave dissipation performance of the breakwater. The vertical position of the center of gravity varies in a large range,while the transmission coefficient has almost no change. As to the effect of pretension,the transmis⁃sion coefficient can be reduced by increasing the pretension in long wavelength region. However ,in the short wave⁃length region,the increase of the pretension raises the transmission coefficient.关键词
