An Engineering consultant appointed on the construction of a Bridge site decided to conduct the Plate load test to get fair idea about the bearing capacity of the sub soil. The test was conducted on a circular plate of 200 mm radius at a depth of 1.20 m below the natural ground surface in pure clayey soil. The failure took place at a load of 55000N. i. Calculate the safe bearing capacity of a 1.2 x 1.4 m rectangular footing founded at a depth of 1.75 m in the same sub-soil. Consider the factor of safety & bulk unit weight unit of 2.25 & 19.8 kN/m' respectively. ii. Highlight any three disadvantages associated with the above in-situ test.
