Spatial variability of soil parameters in an analysis of a strip footing using hypoplastic model
Original language description
Advanced hypoplastic constitutive model is used in probabilistic analyses of a typical geotech- nical problem, strip footing. Spatial variability of soil parameters, rather than state variables, is studied by means of random field Monte-Carlo simulations. The model, including correlation length, was calibrated using a comprehensive set of experimental data. Foundation displacement uy for given load follows closely lognormal distribution, even though some model parameters are distributed normally. The vertical correlation length thétav was found to have minor effect on mý[uy ], but significant effect on sigma[uy ], which decreases with decreasing thétav due to spatial averaging. Applicability of a simpler probabilistic method (FOSM) is also discussed.
