Correction Factor for Soil Poisson's Ratio Rv
The correction factor for the influence of Poisson's ratio Rν accounts for the influence of reduction of Poisson’s ratio ν of soils surrounding the pile on the values of pile settlement for constant modulus of elasticity of these soils. These values are generally presented as a function of Poisson’s ratio of the surrounding soil νs for various K. These graphs are implemented in the program in a digital format.
