Typhoons are violent storms that occur in the tropical oceans of the Northwest Pacific and South China Sea. The waves caused by typhoons are often the strongest dynamic on the coast. The south-eastern coast of China and Japan is in the most frequent and severe area affected by typhoons, and typhoon waves often reach more than 10m. Based on many years’ coastal wave survey data in Japan, it was shown that typhoon waves have been continuously strengthened in the past 100 years, and typhoon tracks and duration have also changed. During the “Mangkhut ” typhoon, many projects along the south China coast were damaged by typhoon waves. Simulation result of the typhoon waves caused by the typhoon showed that the designed wave conditions were exceeded. The physical model is used to reproduce the situation of the breakwater being destroyed by typhoon waves, and analyses the failure mechanism.
