The mean dynamics of a “thick” sand bed in a closed cell filled with
liquid and subjected to vertical vibration is reported at different
amplitudes b and frequencies of vibration for
different grain sizes. The generation of a quasi-steady relief made of a
2D regular system of heaps of relatively small size is found. The
gradual transition from rest to relief formation and after it to
liquefaction and parametrical oscillations of the sand surface with
increasing vibration intensity is studied. The dimensionless
vibrational parameters governing these transitions are determined.
