摘　　要：对斜坡床面上不规则波浪要素及其作用下底部的流动特性进行实验观测,对波高进行统计分析和谱分析,在实验数据范围内得出斜坡上不规则波浪要素与谱的关系表达式,同时对浅化作用下不规则波浪的流动特性进行统计分析和谱分析,得到了浅化作用对不规则波浪的波高及底部流动特性影响的规律.The experimental study of changes of wave height and characteristics of flow field on the slope under irregular waves are carried out. Wave statistic and spectrum analysis are carried out. The relationship between wave statistical characteristics and energy is revealed. Wave statistic and spectrum, characteristics of flow field under shoaling irregular waves are investigated. The results show the characteristics of wave height and flow field under shoaling irregular waves.
