Question
In a plate load test on a soil, at a particular magnitudes of the settlement, it was observed that the bearing pressure beneath the footing is 100kN/m2 and the perimeter shear is 25kN/m2. Correspondingly, the load capacity of a 2 m square footing at the same settlement will be

Solution
The correct option is D 600kN
By an empirical equation given by Housel, Q = Aq + pS
Q = Total load on bearing area
q = Bearing pressure beneath the footing
S = Perimeter shear
A = Area of plate (2×2 m2)
P = perimeter of plate =2×4=8mQ=(2)2(100)+(8)(25)
= 400 + 200 = 600 kN
