Abstract
Horizontally stratified deposit of a sandy soil is characterised using a probabilistic approach. The mechanical behaviour of the soil is described by an advanced hypoplastic model for sand.
The model is calibrated using a set of experimental data on fourty specimens recovered from a quarry wall. It is shown that in order to describe the soil deposit properly using probabilistic approach, spatial variability of soil parameters needs to be considered.
Experimental data allowed us to quantify the spatial correlation structure (measured by the correlation length θ), which is significantly higher in horizontal direction than in vertical direction. The results may be used as an input into numerical methods based on random field theories.
