The article discusses the results of developing an original model for predicting the consequences of the interaction of a snow avalanche with infrastructure elements (buildings). Quantitative results of the impact of a snow avalanche on buildings calculated using the modified Euler-Cauchy numerical method. For a detailed study of the displacement and destruction of buildings by a snow avalanche, a software implementation of an algorithm for solving a mathematical model created. A computer simulation of the destructive impact of a snow avalanche carried out based on official data on an avalanche in the area of the slope of mount «Otdelnaya», settlement Talnakh (satellite city of Norilsk, Krasnoyarsk territory). It shown that the developed model of the impact of an avalanche on infrastructure facilities in an emergency adequately describes the results of snow melting. The results of volumetric modeling of the movement of an avalanche with a volume of several thousand cubic meters presented. The model made it possible not only adequately reproduce displacements of houses that are close to real ones, but also restore a detailed picture of the mechanical behavior of houses under the influence of an avalanche.
