摘要
推移质输沙量是泥沙研究中的一个重要物理量。针对沙质推移质测量存在的难点,采用坑测法原理,通过解决称重、排沙等关键技术,研制出坐底式推移质输沙量实时监测仪,实现了长时间、全天候、实时遥测平原型河流、河口、海岸推移质泥沙输沙量。实验室和现场试验表明,该仪器设计合理、性能稳定、施测便利,可以用于实际工程推移质输沙量监测。
Bed load sediment is an important physical parameter of sediment research. However, bed load measurement is very difficult. Based on the principle of the pit method and to solve the key technology of sedi- ment weighing and delivery, a bed load sediment measuring monitor is developed in this paper. This instru- ment can be used in plain river estuary and coast in real time, all-weather and remotely. The laboratory and field experiments show that the design of this monitor is reasonable and the function is stable. At the same time, it is convenient to operation. As a result, this monitor can be used to observe the bed load sediment transport in engineering.
