1. Calculate the primary consolidation settlement of the 3-m-thick clay layer (see Figure below) that will result from the load carried by a 1.5-m square footing. The clay is normally consolidated. 1) Use 2:1 method and Simpson's rule for calculation of the average Ao' for the clay layer. 890 KN Dry sand Yary = 15.7 kN/m³ 3 m 1.5 m 3 m 1.5 m 1 Footing size 1.5 mx 1.5 m Groundwater table Ysat = 18.9 kN/m³ Clay Ysat 17.3 kN/m³ = 1.0 LL=40 2 vertical to 1 horizontal Aσ = qxBxL (B+z)(L+z) Foundation B xL 2 vertical to 1 horizontal Ag
