摘要
介绍新近试制的飘袋式捕沙器的结构、测量原理、操作方法和输沙率计算程序。在湄洲岛客运码头附近沙滩的应用研究结果表明 ,该种捕沙器可用于现场实测由各种波生流或其它复杂水动力因素产生的沙质沉积物的迁移速率。这对于难以应用模拟计算法取得沉积物输沙率的复杂环境滨海区 。
The structure of the newly developed streamer sand trap, its measuring theory and operating method as well as calculating program of sand transport rate are introduced in the paper. The test results show that streamer trap can be used for measuring the sandy sediment transport rate caused by various wave-induced current or other complicated hydrodynamic factors on site, which provides a better method for measuring the migration amount of sandy sediment in the littoral area, where mathematical modeling technique is hardly applied to.
