Abstract: Experiments to determine the horizontal static bearing capacity are carried out first. The static bearing capacity
is a reference for choosing the amplitudes of dynamic load. Then a series of experiments under dynamic horizontal load
are carried out in laboratory to study the influences of factors, such as the scales of bucket, the amplitude and frequency of
load, the density of soils etc.. The responses of bucket foundations in calcareous sand under horizontal dynamic load are
analyzed according to the experimental results. The displacements of bucket and sand layer are analyzed.
