Small-size artificial ice samples are widely used for ice mechanical properties research， and have the advantages of simple preparation procedures， short duration， low cost， and no seasonal and geographic restrictions. In this paper， the snow pressure sintering experiment was carried out under the conditions of -3.5~-17.3℃ and 10~100MPa， and small-size artificial ice samples were prepared by the pressure sintering method. The results reveal the influence of sintering stress and sintering time on the density evolution during the snow pressure sintering process and the final sintered density of the ice sample. It is concluded that with the pressure sintering method， artificial ice samples with a density of 0.917g/cm³ can be prepared under either of the conditions： a long time， low stress， and near melting point temperature， or a short time， high stress， and low temperature. The experimental results have verified the reliability and repeatability of artificial ice sample preparation with the pressure sintering method and provide a practical and feasible small-size artificial ice sample preparation technique for the experiment of ice mechanical properties.
