摘　　要：The sea bottom in front of a breakwater is scoured under the action of broken waves,and this will affect the stability of the breakwater.In this paper,the scours of sandy seabed in front of a breakwater under the action of broken waves are investigated experimentally.The depth and range of the scouring trough at the foot of a breakwater are studied,and the influence of open foundation-bed on scouring and depositing is also discussed.In order to apply the research results to practical projects,the scale of model sediment and the scale of scours and depositions are suggested.波浪作用下防波堤前海床将发生冲刷 ,进而危及防波堤的安全 .通过试验和理论分析研究了远破波作用下防波堤前沙质海床冲刷 ,包括堤前冲刷深度和范围、基床尺度对堤前冲刷和淤积的影响 .为将研究成果应用于实际工程 ,研究了冲刷相似律 。
