The paper deals with the behaviour of slopes subjected to increasing loads applied to the soil surface just behind the crest. To this end a new fully-automatic small scale 1g physical model has been recently built to reproduce a plain-strain state within a granular soil slope. Two relatively new measurement technologies, namely particle image velocimetry and reverse engineering were used to measure the relevant displacement field in the soil mass and at the slope face. The paper presents the physical model and testing procedure and discusses some preliminary test results.

Abstract
The paper deals with the behaviour of slopes subjected to increasing loads applied to the soil surface just behind the crest. To this end a new fully-automatic small scale 1g physical model has been recently built to reproduce a plain-strain state within a granular soil slope. Two relatively new measurement technologies, namely particle image velocimetry and reverse engineering were used to measure the relevant displacement field in the soil mass and at the slope face. The paper presents the physical model and testing procedure and discusses some preliminary test results.
