Description
Summary:This paper presents the details of an air pluviation system suitable for preparing large-scale uniform sand specimens for conducting various types of laboratory test models namely static or dynamic tests on footings, piles, and liquefaction. A series of laboratory tests on three types of uniformly graded sands with average particle size (D 50 ) of 0.27 to 0.90 mm were performed to study the effect of perforated plate (PP) porosity on the relative density (RD) and deposition intensity (DI). To this aim, two practical graphs were elicited which show the variation of RD and DI versus normalized values of PP holes’ diameter with average particle size (PP/D 50 ). Accordingly, for PP/D 50
