A1-m-wide surface-supported strip footing carries a loading of 100 kN per meter of wall length. Determine the total vertical stress acting at a depth of 1 m below the center of the foundation width (note that the total stress will be the sum of the original vertical stress due to the soil mass plus the increase due to the foundation loading). Assume the Boussinesq conditions apply. Use a soil unit weight equal to 18 kN/m3.
Calculate the passive earth pressure coefficient for the foundation soil to the right of thetoe of the wall using the Rankine Earth Pressure theory. On Figure 1, sketch the passivepressure distribution and calculate the resultant force(s). Show the resultant, and itslocation, on your sketch.AND Sketch the wall and the distribution of lateral earth pressures resulting from the backfillfor the Coulomb case, assuming good drainage. Call this “Figure 2: Coulomb Active EarthPressures from Backfill.” Calculate the resultant horizontal and vertical forces and addthem to your sketch. Indicate clearly the location of the resultant forces.

Hi guys please help me answer this question with detailed solution. Thank you A small unyielding wall retains a dense cohesionless soil with no lateral movements of soil (at rest conditioned is assumed). the wall has a height of 2.5 m. the cohesionless soil has a unit weight of 16 kN/m3 and a saturated unit weight of 18.39 kn/m3. Angle of internal friction is 37 degrees. The ground water table is located 1.0 m below the ground level. A. Compute the lateral force acting on the wall B. Compute the location of the total lateral force above the bottom of the wall C. Compute the moment acting on the wall due to this lateral load
