vibrations on the hydroelastic model. The location of the waterfall was also placed 7 m from the end of the downstream section of the hydroelastic model. Fig. 4 shows the vibration isolation and reduction measures used for our model. Fig. 4 Vibration isolation and reduction measures of the model A hydroelastic model of Xiangjiaba hydropower station with energy dissipation via a hydraulic jump was built on the test platform (Fig. 5). The geometry scale of the model was 1:80, and the simulation context included the overflow section of the dam, two stilling pools and a section of its foundation. According to the requirements of the model material property similarity law, synthetic rubber was used as the prototype material. The arrangement of the vibration acceleration measurement points located on the model are shown in Fig. 6.
