从模型沙几何形状、静水和动水环境下的性质及模型沙的适用性，讨论了模型沙性质研究现状。该课题的研究是有理论和实际意义的，目前的研究还停留在满足生产需要的水平上，今后需要继续加强。
The current research on the properties of model sand is discussed from the aspects of the geometry of the model sand, the properties in the still and moving water environment and the applicability of the model sand. The research of this subject is of theoretical and practical significance. The current research is still at the level of meeting production needs and needs to be further strengthened in the future.
