In Fig. 11, permanent horizontal displacement distributions of the rubble mound level (zZ120 mm)and the sand layer under the rubble (zZ80 mm) are plotted for both cases together with physical model test result (PW3). The displacements for the physical model test were obtained from the movements of the noodle targets placed between the transparent window of the container and the model grounds.
