本文介绍了海滩及近岸浅水区使用的两种推移质捕沙器的结构及使用方法,并分析了部分测量结果。测量表明,中潮线以下海滩及近岸浅水区内,推移质沙的运动方向基本上和波能的传递方向一致。据此关系,提出了直接运用波能流和推移质沙量的函数关系来计算推移质输沙量的方法,它不同于常用的只利用波能的沿岸分量的计算方法。 This paper introduces the structure and application of two types of pumped bed traps used in beaches and coastal shallow waters, and analyzes some of them. The measurements show that the movement direction of the sediment-laden sediment is basically consistent with that of the wave energy in the beaches below the mid-tide line and in the shallow coastal waters. Based on this relationship, a method of calculating the sediment transport by using the function of wave energy and pumped sediment mass directly is proposed, which is different from the commonly used method of calculating the coastal component using only wave energy.
