Abstract: Three-dimensional deterministic model of thin elastic shell on a rigid underlying surface of arbitrary configuration is used as approach to a snow slab on the mountain slope. The finite difference method is used for calculation of stress distributions in the snow cover. Spatial distributions of snow cover characteristics are represented as stochastic fields which realizations are simulated with Monte Carlo method. Such characteristics as snow thickness, density and cohesion were simulated on a base of information about spatial statistical structure of these parameters to obtain a stress field over a slope.
