摘要：

本文对立波作用下直立堤前冲刷模型比尺进行了研究,利用堤前冲刷形态的判别标准,给出了模型沙的取值范围。根据泥沙运动连续方程,考虑立波作用下堤前冲刷机理,导出了堤前冲坑比尺关系。

The model scale of the scour in front of breakwater was discussed. The range of the model sand grain size was obtained by using the distinquishing criteria of scouring patterns in front of a vertical breakwater. The scouring scale at the foot of breakwater was derived by employing the conservation equation of sediment mass and considering the mechanics of scour in front of breakwater.
