THE SIMULATION TESTING ON FLOWING SAND

This thesis introduces a way to decide the scale of the sand model. The experiments phenomena of two modelsis preseated and explained. The experiments data show the distribution of the water head and the seepage gradient near the flowing sand channel. Additionally, the effects,by the sand porosity, the weight of the overlaid soil and the ascending speed of the seepage Bead produce on flowing sand, are reoorgnized by contrasting experiments.
