Shaking table tests on gravel slopes reinforced by ...

2020-8-1  To accurately simulate the dynamic response of a reinforced slope, appropriate similitude rules are required for the test. In this study, the similitude laws presented by Iai (1989) were used; these laws are widely adopted, being employed in many 1-g model tests. In accordance with the bearing capacity of the shaking table, the similarity ratio to the geometric size was determined to be 1:6.
