Abstract: A new ice-hydrodynamics experimental platform which could carry out real ice experiments was developed to overcome disadvantages of traditional experiment. The lowest air temperature of platform can reach-15℃, the precision is 0.5℃, unevenness is less than 1 ℃ (the difference between the maximum and minimum values). This platform greatly improves precision and efficiency of ice experiment, and provides a new way to research complex ice problems in winter. The platform includes experiment control SCADA system (Supervisory Control and Data Acquisition system), temperature control SCADA system, demountable circulating flume, variable speed pump system, variable speed ice supply system, gate control system, and so on. Automatic control and real-time data collection of water level, discharge, gate’s action and ice discharge are also realized. By ice accumulation experiments of the Tanghe inverted siphon which is a hydraulic structure of the central line of South to North Water Diversion Project, precision and reliability of platform are proved.
