A wall is supported on a 1.0 m wide strip footing located 1.5 m below the ground surface. The surrounding soil has a dry unit weight of 17.5 kN/m3, a saturated unit weight of 19.0 kN/m3, cohesion of 8 kPa and angle of internal friction of 26°. Groundwater was located 2m below ground surface. Using a factor of safety of 3, determine the allowable bearing capacity if a) the footing is considered infinitely long, and b) the footing is 8 m long.
