【Abstract】 Following a series of experimental study on the hydraulic performance of the new comb type vertical breakwater, the hydraulic characteristics of this new type structure and its effects on the reduction of the wave reflection and the exciting wave forces on breakwater were analyzed. An empirical formula for the calculation of force ratio between wave force on unit length of comb type structure and that on unit length of traditional vertical wall, i. e., the reduction coefficient of wave force on comb type breakwater was given, which can be used in the determination of main parameters of comb type structure and also can be used in the preliminary calculation of wave force on this new type breakwater. This comb type structure has been constructed in the island breakwater project at the Dayao Bay of the Dalian Port, the wave force on comb type structure is only at a rate of 62～73% of the wave force on traditional type vertical wall and the investment can be reduced by 24.5%.更多还原
