A new form of breakwater is proposed according to the design of marina project of Bazhuayu hotel in Longmu bay,Hainan province.Glass curtain walls are installed on the top of breakwaters to enhance the capacity of wave attenuation.Sectional experiments of physical models are conducted to obtain data of different combinations,including wave height behind the breakwater,wave-overtopping discharge,pressure on the glass curtain wall.Results show that the capacity of wave attenuation is improved by new breakwater.Besides,fulfilling the need for aesthetics,the breakwater could provide appropriate wave height condition inside the harbor area,which makes promotion worthwhile.
