摘　　要：文中利用SPH的方法建立数值水槽,通过与实验结果进行对比,证明了SPH数值水槽模拟的有效性,对波浪在陡坡传播的破碎过程进行数值模拟,发现传播速度较大的时候,卷舌在撞击回流的波浪后会出现二次卷舌的现象.并从流场和涡量方面分析了规则波在陡坡上波浪传播破碎的演化过程,更进一步证明了基于SPH方法数值水槽在用于陡坡的波浪传播模拟实验的精确性.The numerical flume was established by SPH method,and the effectiveness of SPH numeri-cal flume simulation was proved by comparing with the experimental results.The numerical simula-tion of the breaking process of wave propagation on steep slope shows that when the propagation speed is high,the tongue rolling will appear the phenomenon of secondary tongue rolling after hitting the returning wave.The evolution process of regular wave propagation and breaking on steep slope is analyzed from the aspects of flow field and vorticity,which further proves the accuracy of numerical flume based on SPH method in wave propagation simulation experiment on steep slope.
