摘要
本文在前文全面总结模型沙性质现有研究成果的基础上，对细颗粒模型沙的部分性质进行了对比研究，如水下固结特点、流变特性、直接快剪的特性及水下固结时间对起动流速的影响，并对细颗粒泥沙、粘性泥沙的概念进行了讨论，这些对泥沙实体模型试验有一定的参考价值，并对今后的研究有一定的指导作用。
On the basis of comprehensive summarizmg the present results of model sand studied, some aspects for finer model sand, such as the consolidation under water, the rheological property, the characteristics in direct shear test and effect of consolidation under water on threshold velocity have been investigated in the paper, These have some significances for model sand selection in a practical model test and can be taken as a guide for further study on characteristics of model sand.
