One type of transducer (acceleration sensors (A1-A3)) was used to measure the acceleration and its results integrated to draw shear stress graph. Test Procedure of Experimental are following as - The filter plates were fixed and sealed on top of baffle walls inside the acrylic box. - The aluminum channels were fixed with gum tape inside the acrylic box. - Signal conditioner of acceleration sensor was switched. - The prepared sand was laid. - Acceleration sensors were placed at required locations. - The colored sand was laid at every 10 cm height horizontally and at 10 cm vertically in aluminum channels. - The water was allowed through baffle walls at very slow rate for saturating the ground. - The shaking was carried out uniformly. - The results recorded in the computer and created in the form of the graphs.
