Shear strength of clay, C (Pa)
The influence of shear strength of the underlying clay on the bearing capacity.
3.5 Deformation and Displacement of the Continuum Materials
The deformed shape of the finite difference grid, representing the super soft clay, the
reinforcement, and the overlying sand, and the directions of the principal stresses are
shown in Figure 11. The data are derived from test f-20 at s/B = 0.3 (Table 1).
