This paper contains the experimental results of a series of shaking table tests of a model of gravity retaining wall, with the purpose to investigate the distribution of dynamic earth pressure in dry cohesionless backfill and the effects of the soil-wall friction on the distribution of pressure. All the tests were conducted at the University of Catania shaking table. The models were instrumented to measure displacements, accelerations and dynamic pressure. The results of the experimental program show that the dynamic earth pressure distribution is influenced by the wall movement modes and the point of application of the active thrust is always near the top of the wall. The reduction of the wall friction produces an increment of dynamic pressure, influencing the failure mode of the soil-wall system. All the recorded pressure shows a non linear distribution with depth.
