The L-shaped retaining wall shown retains soil on the right side and water on the left side is to
be analyzed. Fluid pressure is shown with bottom pressure equal to P₁ acting on the left side of the wall. Soil
pressure is also shown with bottom pressures P2 and P3, acting on the right sides of the wall. Trapezoidal uplift
pressure due to seepage is acting at the bottom of the wall with pressure P4 on the side of the water (on point
A) and Ps on point B. The horizontal part of the wall is also subjected to the weight of the soil above it with
magnitude P6. The wall is made of concrete with unit weight 23.5 kN/m³. Assume 1 meter width for the analysis
and include the self-weight of the structure.
