摘要
本文对立波作用下沙质海岸直立堤前相对粗沙型冲刷形态冲刷问题进行了实验研究,重点研究了突基床尺度变化对堤前冲坑的影响。首先给出了暗基床直立堤堤前冲坑经验公式;其次研究了突基床宽度、高度、对堤前冲坑的影响规律,并提出了突基床防波堤堤前冲坑计算方法。
Experiment were carried out on the effects of mound size on the scours in front of breakwaters. The experimental formula for calculating the maximum depth of the scouring trough at the foot of a vertical break water was presented. The influence of the width and height of mound on the scouring trough was probed. A calculating method in maximum depth of the trough has been developed.
