4. A strip footing of width 3 m is founded at a depth of 2 m below the ground surface in a (c - Ø) soil having a cohesion c = 30 kN/m² and angle of shearing resistance ø= 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 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. 5. If the soil in Q4 fails by local shear failure, determine the net safe bearing pressure. All the other data given in Q4 remain the same. 6. If the water table in Q4 rises to the ground level, determine the net safe bearing pressure of the footing. All the other data given in Q4 remain the same. Assume the saturated unit weight of the soil Ysat 18.5 kN/m³. 7. If the water table in Q4 occupies any of the positions (a) 1.25 m below ground level or (b) 1.25 m below the base level of the foundation, what will be the net safe bearing pressure? Assume Ysat = 18.5 kN/m³, y (above WT) = 17.5 kN/m³. All the other data remain the same as given in Q4.
