A rectangular foundation 2.5m × 6m on a deposit of overconsolidated sandy gravel with past overburden pressure of 150 kPa is shown in the figure below along with the variation of the cone penetration resistance. Assuming that the bulk unit weight of the sandy gravel is 18 kN/m3and creep is at the end of ten years after construction, calculate the elastic settlement of the foundation using the strain influence factor method
