Question
A square footing of size 2.5 m x 2.5 m is placed 1.0 m below the ground surface on
a cohesionless homogeneous soil stratum. Considering that the groundwater table is
located at the base of the footing, the unit weights of soil above and below the
groundwater table are 18 kN/m³ and 20 kN/m³, respectively, and the bearing capacity
factor N is 58, the net ultimate bearing capacity of the soil is estimated as 1706 kPa
(unit weight of water = 10 kN/m³).
Earlier, a plate load test was carried out with a circular plate of 30 cm diameter in the
same foundation pit during a dry season, when the water table was located beyond the
plate influence zone. Using Terzaghi's bearing capacity formulation, what is the ultimate
bearing capacity (in kPa) of the plate?
