This cantilever wall has moved sufficiently to create the active condition. Compute the lateral pressure distribution acting on this wall with the groundwater table at locations a and b, as shown in Figure 16.17. The soil properties are: c^{\prime } = 0, Φ^{\prime } = 30°, γ = 20.4 kN/m^{3}, and γ_{sat} = 22.0 kN/m^{3}
