摘　　要：应用光滑粒子流体动力学(SPH)方法,建立了模拟波浪作用下双方箱浮防波堤运动响应的数值模型,计算了其透射系数、反射系数和运动响应,数值模拟与试验结果符合较好。通过数值计算分析了双方箱浮防波堤在不同入射波周期和不同锚固方式下的水动力特性。数值计算结果表明:平行锚固和交叉锚固的双方箱浮防波堤相比,二者的透射系数相近,但交叉锚固方式的运动幅值和锚链力要略大于平行锚固方式。Smoothed particle hydrodynamics（SPH） is used to build a numerical model that simulates the motion response of dual pontoons floating breakwater under wave action. The numerical model calculates its transmission/reflection coefficients and motion response. Numerical simulation accords with the experimental results. In addition, the numerical calculation is carried out to analyze the hydrodynamic characteristics of dual pontoons floating breakwater under the conditions of different incident wave periods and anchoring ways. The numerical calculation results lead to similar transmission coefficients of dual pontoons floating breakwaters in cross and parallel anchoring ways, but the motion range and anchoring force of the former one are slightly larger than that of the latter one.
