Artificially synthesized transparent soil materials combined with particle image processing technique has been widely used in model testing. However, further study of pile foundation scour and research on its characteristics is essential. Based on the transparent sand prepared by the mixture of fused silica sand, twelve alkane and 15# white mineral oil, the basic physical properties, angle of repose and starting velocity of the transparent sand were studied through laboratory experiments. The results show that the transparency of the mixture is not much different except for the 1-2 mm particle size group which is significantly worse; the bulk density of transparent sand in each particle size group is of slight difference; the bulk density of transparent sand in each particle size group is also of neglectable difference; dry bulk density increases first and then decreases with the increase of particle size; the pore liquid shear rate and shear stress show a good linear relationship, which is a typical Newtonian fluid; the submerged angle of repose increases with increase of the median diameter; the initiation velocity of transparent sand with a particle size group of 0.1-0.2 mm increases with increase of liquid depth, fitting by Shamov's formula, indicating the better anastomosis effect.
