Submerged Stiff Clay
The following material properties need to be defined for the p-y curves to be created (Reese, et al., 1975):
- Strain Factor (E50) - strain corresponding to 1/2 the maximum principal stress difference. Typical values are provided below.
- Undrained Shear Strength
- ks - refer to the theory manual for further description (typical values provided in the table below)
The diameter of the pile and depth into the soil has a direct impact as well. See the Lateral Pile Theory Manual for more information.

REPRESENTATIVE VALUES OF E50 FOR OVERCONSOLIDATED CLAYS
Average undrained shear strength (kPa) | 50-100 | 100-200 | 200-400 |
E50 | 0.007 | 0.005 | 0.004 |
REPRESENTATIVE VALUES OF KS FOR OVERCONSOLIDATED CLAYS
Average undrained shear strength (kPa) | 50-100 | 100-200 | 200-400 |
ks (MN/m3) | 135 | 270 | 540 |
