6.3 Stability of rockfill dam
In Japan, the first centrifugal model test for rockfill dam was conducted by Osaka City University in 1969 for Kisen-yama Dam, in Kyoto. Before starting a series of tests, two special devices were developed; one is for causing a sudden lowering of water table using fluid slip rings and the other is for loading static horizontal forces, equivalent to the earthquake forces, by tilting the model container during the flight. A failure pattern for 32.5 m-high dam is shown in Photo 1.
