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。
Sediment transport sediment is an important physical quantity in sediment research. Aiming at the difficulties in the measurement of sediment pushover quality, the pit-measure principle is adopted to develop the real-time monitor of sediment transport displacement by solving the key technologies such as weighing and sediment discharge, and realizes the long-time, all-weather, real-time telemetry Plain rivers, estuaries and coast sediment sediment transport capacity. Laboratory and field tests show that the instrument is reasonable in design, stable in performance and convenient in application and measurement, and can be used for monitoring the quality of sediment transported by the actual project.
