Based on the analysis of wave elements of waters around Dalian offshore airport artificial island,we carry out the physical model experiment on the wave overtopping of the artificial island’s retain wave wall with different wave directions using JONSWAP spectrum.The results show that,for the design retain wave wall section,the wave overtopping of different directions can meet the design requirements in the case of 100 a and 200 a of the wave return period under the extreme high water level.The experimental results provide a scientific basis for optimizing the artificial island revetment structure.
