Question 2: (40 points) A 2.4mx3m rectangular foundation has to be constructed. The plan and side views of the footing are shown in the figures. The ground water level is at 0.5m depth. The soil supporting the footing has s'=25°, c'=20kPa, y=16.5kN/m and Ysat=19kN/mº. The depth of foundation is 1.5m. Total gross vertical load acting on the foundation is given as 1500KN. The eccentricity (e) is given as 0.2m as shown in the figure, a) Calculate the ultimate bearing capacity (qı) by using general bearing capacity formulation b) Calculate the base pressures at points A and D. (Take 122=3.456m^) c) State, if foundation is safe or not. (Take FS=3 and find Call gross = Note you can assume that the settlement of the footing is less than allowable settlement). (Note: Use gross pressures and capacity). (Hint: Use effective dimensions (B' =B-2e) in calculation of shape factors and real dimensions in calculation of depth factors.)
