For soil:
TH( K)= Distance from ground surface to the end of the layer ( feet)
DIA( K)= Diameter of shaft at the mid- height of the layer ( inches)
GAM( K) = Effective or total unit weight of soil at the mid- height
of the layer ( pcf)
FPHI( K)= Angle of internal friction soil at the mid- height of the
layer, ( degrees).
SK( K) = Coefficient of lateral subgrade reaction at the mid- height
of the layer, ( pci).
CSHO( K) = Undrained shear strength of the soil at the mid- height
of the layer, ( psi)
EP50 ( K) = Strain corresponding to 50% stress level at the mid-height
of the layer
NPC( K) = Code to control the type of P- y curves to be generated:
= - 1, P- y curves are generated using the Unified method.
= 0, P- y curves are generated using the procedure
developed by Reese et al. for sand.
= 1, P- y curves are generated using the procedure
developed by Parker et al. and O’Neill et al. for soil layer
possessing both friction angle and cohesion.
For rock:
TH( K)= Distance from ground surface to the end of layer ( feet).
DIA( K)= Diameter of shaft at the mid- height of the layer ( inches).
GAM( K) = Effective or total unit weight of rock at the mid- height
of the layer ( pcf).
FPHI( K)= GSI value of rock at the mid- height of the layer.
SK( K) = mi value of rock at the mid- height of the layer.
CSHO( K) = Unconfined compressive strength of rock at the mid-height
of the layer, ( psi).
EP50 ( K) = 0.00 for the rock sub- layer
NPC( K)= Code to control the type of P- y curves to be generated:
= - 4 P- y curves generated using the Weathered Rock

RR ( J) = EI value ( psi)
