Experimental Investigation and Analysis of the Settlement Funnel in Beds Supporting Different Types of Foundations

Settlement of shallow footings on layered soil: state-of-the-art

“…Change of parameters in one layer affected the consolidation behavior of another layer due to different consolidation rates. Shvets et al (2003) presented a solution to determine the stresses in a foundation bed, which was represented by a linearly deformable half-space and intended for foundations with circular or square lower surfaces extending beyond the limits of the loaded area. The experiments were conducted on cohesive and non-cohesive soils of homogeneous and layered beds to investigate the formation of the settlement funnel.…”
