摘要

传统的悬移质输沙率人工测验方式耗时耗力,效率低下。论述了在南宁水文站开展自动化走航式全断面积宽法悬移质输沙率测验的研究过程和方法,通过对应浊度试验传感器悬移质断面平均含沙量的比测,建立新的断沙关系模型;通过对浊度传感器悬移质单样含沙量的比测,建立新的单断沙关系模型。从而实现测流测沙一体化,达到悬移质输沙率自动监测的目的。
        Traditional suspended sediment discharge test is conducted manually and inefficiently. Suspended sediment discharge test was conducted at Nanning Hydrological Station by automatic navigation full-section area width method. An introduction was made on the procedures and method of test. Comparison measurement of average sectional suspended sediment concentration and single sample suspended sediment concentration were carried out for the turbidity sensors, based on which new section-sediment relationship model and single section-sediment relationship model were established, so as to realize integrated measurement of flow and sediment as well as automatic monitoring of suspended sediment discharge.
