“…Over the past decade, this sand has been subjected to intensive conventional laboratory and Calibration Chamber testing. The results of such tests have been reported by Baldi et al [9,10,11], Bellotti [12,4] and Lo Presti et al [13].…”

“…This approach considers a depth of influence, equal to two times the foundation width B for square footing. The soil layer having thickness 2B is subdivided in strata of height ~-The total settlement ( w) is computed by means of the following expression: (4) where: t:.q = q-cr~., i.e. net pressure increment ( cr~.…”
