HOW TO CALCULATE SAFE BEARING CAPACITY OF SOIL ON SITE? BG BUILDERS - THANJAVUR - 94434-76585 This simple and quick field test will give you a rough idea of bearing capacity of soil. Procedure Excavate a pit of required depth. (preferably equal to the depth of foundation) Take a solid ball or square cube of known weight and dimension. Drop the ball or square cube several times, from a known height on to the bottom surface of excavated pit. Calculate the average depth of impression made several times on the bottom surface of the excavated pit. Let “d” is the average depth of impression. Calculation Calculate the ultimate resistance of soil ( R ) using the formula given below. R = (w * h) / d Where, R = Ultimate resistance of soil (in kg) d = Average depth of impression (in cm) w = Weight of the solid ball or square cube (in kg) h = Height of fall of...
