Estimation of Soil Constitutive Parameters

  The parameters of the soil constitutive model to be employed for numerical simulations are evaluated at each spatial location (finite element centroid) over the analysis domain, based on simulated in-situ test values (Fig. 1b). An automated procedure was implemented to estimate the parameters of a multi-yield plasticity model (Prevost (1985)) from cone penetration or standard penetration test results. The user is prompted to select from a large number of empirical correlation formulas reported in the literature (e.g. Prevost and Popescu (1996)) those correlations which best suit the specific soil materials used in the application.
