ADCP在泥沙扩散测验中的应用

Application of ADCP in Sediment Diffusion Tests

为进一步弄清广州港南沙港区航道试挖槽上游采沙船作业产生的泥沙扩散对试挖槽泥沙田淤的影响,长江下游水文水资源勘测局采用ADCP对采沙船作业引起的泥沙扩散进行了观测。根据观测资料分析,采用ADCP进行施测分析是完全是可行的,不仅对挖沙施工影响(吸沙和洗沙)产生的泥沙扩散进行了从点、线和面全方位进行了的定性和定量跟踪测量,而且提高了精度降低了成本。

In order to make clear the influences of sediment diffusion caused by sand sampling boats on back-suilting of trial chamfers of sea routs in Nansha Port of Guangzhou Harbor, Lower Reach Bureau of Hydrology and water resources surveying of Yangtze River Water Resources Committee adopted ADCP to test the sediment diffusion. Through analysis on measuring data, ADCP is proved to be a feasible method which can not only track and measure sediment diffusion on points, lines and areas from quantity and quantity, but also raise precision of measurement and reduce costs.
