Abstract: The influence of the sand particle size on the compressive strength of the analog model study is always ignored in analog simulations. This omission leads to the difficulty of finding the matching ratio of the model. The impact of the particle size of the sand on the compressive strength in the analog model studies with other factors remain unchanged. The results indicate compressive strength of the model is reversely related to the particle size of the sand. The impact of the particle size on the strength is proportional to the cementation of the sand material.
