Plate load test is adopted globally to determine in-situ bearing capacity of the subsoil and considered as one of the most important field test for any big construction project. A plate load test was conducted on a 300 mm side square plate at a depth of 1.10 m below the ground level in pure clayey soil for an important construction site. Failure of the soil occurred at a load of 45 kN. i. Calculate the safe bearing capacity of a 1.5 m wide square footing founded at a depth of 1.5 m in the same sub-soil. Assume the total unit weight and factor of safety of 18.2 kN/m and 2.0 respectively. ii. State any three limitations of the above mentioned test carried in field.
