The theoretical procedures described herein have been applied to tests of a model of a rockfill
dam, described by Davis et al. (1960). The scale of the model was l/300 of the prototype.
The dynamic tests of the model were made by striking a shaking table with a heavy pendulum.
A rebound of the pendulum caused a second input at a lower acceleration. Hence, data could
be obtained both for the initial strike and for the first rebound.
On the whole, the model tests indicated a fair agreement with the calculations, for comparable
conditions. Within the accuracy of the records obtained in the tests, the measured
motions were in fairly good agreement with the results computed by means of equation (23)
and Fig. 21.
