A 3.0m wide, but long base of a retaining wall, is founded 1.0m below the ground surface. The water table is well below the base level. The vertical and horizontal components of the base reactions are 285kN/m and 100kN/m respectively. The eccentricity of the base reaction is 0.4m. Representative shear strength parameters for the foundation soil are c' = 0 and Ф' = 35degrees. The unit weight of the soil is 18kN/m3. Determine: The ultimate bearing capacity/pressure on the foundation soil The net ultimate bearing pressure

Question
A 3.0m wide, but long base of a retaining wall, is founded 1.0m below the ground surface. The water table is well below the base level. The vertical and horizontal components of the base reactions are 285kN/m and 100kN/m respectively. The eccentricity of the base reaction is 0.4m. Representative shear strength parameters for the foundation soil are c' = 0 and Ф' = 35degrees. The unit weight of the soil is 18kN/m3. Determine:
- The ultimate bearing capacity/pressure on the foundation soil
- The net ultimate bearing pressure
