Abstract
The present study elaborates the preparation of large volume sand bed at different height of fall and deposition intensity for two different types of Indian River sands using the air pluviation methodology. Reconstitution of sand bed is crucial in case of model scale testing to produce the outcomes ensuring repeatability and reproducibility. A systematic study has been carried out in order to determine the optimized area of orifice opening which can fetch the maximum deposition intensity for the given effective area of the sieve plate. In the present study, the scale down model of Jornada dynamic penetrometer at different locations of the test tank has been employed to quantify the soil resistance and to qualify the uniformity of placement density throughout the sand bed at different height of fall. The study also reveals that sand beds of wide range of relative densities can be achieved at different deposition intensity employing different sieve plates.
