A strip footing of width 3 m is founded at a depth of 2 m below the ground surface in a (c – 0) soil having a cohesion c = 30 kN/m2 and angle of shearing resistance 0 = 35°. The water table is at a depth of 5 m below ground level. The moist weight of soil above the water table is 17.25 kN/m3. Determine (a) the find ultimate bearing capacity of the soil, (b) the net bearing capacity, and (c) the net allowable bearing pressure and the load/m for a factor of safety of 3. Use the general shear failure theory of Terzaghi
