| 摘 要： | 洋山深水港地形差异大,流态复杂,在宽阔的西口门和窄深东口门,以传统方法同步开展悬沙输移监测十分困难。详述了在颗珠山汊道应用ADCP走航测沙的实现方法,结论显示,与传统代表垂线法成果相比,通过ADCP声反向散射信号计算的垂线平均含沙量,其对比标准差约为6%,随机不确定度在12%(置信水平为95%)左右,误差分布基本成正态,两种方法之间的断面输沙率相关系数达到0.96,可见,利用ADCP的声反向散射信号,只要标定得当,在洋山港区得到的垂线平均含沙量和断面输沙率是可信的,该技术将为洋山港区关键控制断面悬沙监测提供新思路。 |

| Abstract: | Yangshan deep-water port possesses great variation in topographic,and the flow regime is complex.Synchronical monitoring of the suspended sediment transport by using traditional methods is very difficult in the broad west section and the narrow deep east section.Application of ADCP backscatter was made to estimate suspended sediment concentration at Kezhushan inlet.It was found that comparing the traditional results with the estimation from ADCP backscatter,the standard deviation is about 6% and the uncerta... |
