Typhoon waves often occur at different levels near the coast of Shandong, posing a great threat to human life, property and infrastructure. Therefore, it is of great practical significance to analyze the risk of typhoon waves in Shandong Peninsula. In this study, the ADCIRC+SWAN coupled numerical model is used to simulate the wave process during the passage of 36 typhoons from 1979 to 2018, which is driven by the combination of Holland model wind field and NCEP reanalysis wind field. Taking the maximum significant wave height of typhoon as the risk evaluation index, the distribution of typhoon wave intensity, duration frequency and risk index in Shandong Peninsula are given. The results show that the northern part of Shandong Peninsula is a low risk area for typhoon waves, with low intensity and short duration; In the south, typhoon waves above the level 2 intensity (the significant wave height range is 1.3-2.5m) occur more frequently, and the risk is higher than that in the north; The intensity of typhoon wave in the east can reach level 4 (the significant wave height is above 4m), and the risk of typhoon wave in this area is the highest.
