Question

PLEASE ONLY SOLVE PROBLEM 4 Please explain the theory and concept behind this problem so I can understand, please show clear and neat handwriting/calculations 

3.Define the allowable bearing capacity of a circular foundation of a radius 2R=10 ft using the Terzaghi's bearing capacity equation for a local failure. In your calculations assume two scenarios: a) that the ground water table matches the bottom of the foundation, and b) that the ground water table is 6 ft below the bottom of the foundation. Use a factor of safety of 2.8, and the dry unit weight above the ground water table. 6 ft 10 ft 20 ft 2R ROCK SAND D = 36 G=2.67 e = 0.6 CLAY C=0.75 e = 0.9 Y sa: 132 pcf 6 ft a) gall. B) gall = 1565psf = 1502 psfi 4. Design the foundation in Problem 3 (find the radius), for the assumptions that the failure is general, sand is dry, loading Q-6000 kN, and the factory of safety is 2.4. += 4.8 ft
