摘　　要：A structure scheme of a pile-based breakwater with integrated oscillating water column(OWC)energy conversion chamber was proposed,and four structure forms had been designed.Based on the physical test,the variations of the reflected wave height,the transmitted wave height,the air velocity at the outlet of the chamber,the air pressure and the wave height in the air chamber were studied under the conditions of different wave heights,periods,with or without elliptical front wall and the baffles on both sides of the chamber.Moreover,based on the results,the changes and relationship between the wave-eliminating effect and energy conversion effect of the scheme were analyzed.In general,it turns out,the transmission coefficients of the four structure forms are kept below 0.5.Furthermore,the transmission coefficients of the structural forms G2,G3,and G4 were all smaller than 0.4,and it is only 0.1 at its smallest.Thereinto,in general,the structure form G4 has the best wave-eliminating and energy conversion performance.At the same time,when the wave steepness is 0.066,the energy conversion and wave dissipation effect of the four structure forms is the best.The research results could be provided as the reference for the design structure selection of pile-based breakwater with integrated OWC energy conversion chamber.
