Calculation of Winkler-Pasternak Parameters C1 and C2 from Geological Profile
A characteristic combination of load must be chosen when calculating the Winkler-Pasternak parameters (C1, C2) from geological profile. This combination should be considered as service and should correspond to the most frequently appearing load. Using this combination, a surcharge at the footing bottom is calculated next followed by calculation of the influence zone.
Deformation parameters (Poisson's ratio, deformation modulus) are determined for the calculated influence zone as a weighted average of deformation parameters of soils. Given these parameters the Winkler-Pasternak constants (C1, C2) are then calculated in the following way.
