摘　　要：针对实际海浪是随机的情况 ,本文首次研究了不规则破碎波作用下直立堤前沙质海床的冲刷。通过水槽试验 ,揭示了不同水深、不同波谱。The waves in front of breakwaters are irregular and classified into non breaking waves and breaking (broken) waves. In this paper the scouring patterns of sand bed in front of vertical breakwaters under the action of irregular broken waves were investigated. Based on the experimental data in the condition of different water depths, different wave spectra, different sand sizes and different seabed slopes, the scouring patterns in front of breakwaters under the action of irregular broken waves were given.
