Effect on the Grain Size Distribution when Preparing Sand Using Poker Vibrators

At Aalborg University and other research institutions, model tests are performed on small -scale foundations. These foundations are often installed in sand which has to be prepared in a reproductive way. At Aalborg University the preparation is done by using poker vibrators. This paper investigates if this preparation technique affect the soil in regards to grain size distribution, homogeneity and stratification. The paper concludes that the preparation technique does not lead to any change of the soil.
