A building of very great length has a width of 36 m. Its weight constitutes an applied stress of 240 kPa on the ground surface. Between the depths of 21 and 27 m there is a layer of soft clay. The rest of the subsoil is dense sand. Compute the applied vertical pressure due to the weight of the building, at the following points located in a horizontal plane at mid-height of the compressible layer: directly below centerline of building; and 6, 12 and 18 m from the centerline Directly below the centerline: I= Δσ =
6 m from centerline: I= Δσ =
12 m from centerline: I= Δσ =
18 m from centerline: I= Δσ =
