“…In this solution, the geometry of Hill's plane strain mechanism (Hill, 1950) was used to simulate continuous axisymmetric displacements. Shield (1955a) presented a complete solution for a smooth circular footing on a purely cohesive soil, and Eason & Shield (1960) extended the same solution to the case of a perfectly rough footing. Cox et al (1961) solved a number of cases of the circular surface footing on c-ö weightless soil.…”

A kinematic plastic solution has been developed for the penetration of a circular footing into an incompressible soil bed. In this solution, the pattern of deformation around the footing is idealised by a simple plastic deformation mechanism. Strain-hardening behaviour and nonlinear stress-strain characteristics are incorporated. This application is different from conventional applications of plasticity theory as it can approximately predict both stresses and displacements under working conditions. This approach therefore provides a unified solution for design problems in which both serviceability and safety requirements are based directly on the stress-strain behaviour of the soil. The design strength that should limit the deformations can be selected from the actual stressstrain data recorded from a carefully specified location, and not derived using empirical safety factors. The validity of this design approach is examined against nonlinear finite element analyses and field measurements of foundations on clay under short-term loading.

“…N c is the bearing capacity factor of the circle footing and varies with the embedment ratio. The value of the surface of the foundation resting on cohesive and frictionless soil is 6.05 [3]. s u,tip is the undrained shear strength of the soil at the foundation tip level, s u,av is the average undrained shear strength over the penetration depth.…”
