This article deals with the stability of the snow cover in a simplified case of a two layer stratification including a cohesive layer laying on a weak layer. A parametric study at a macroscopic scale is presented, as well as a study of the coupling mechanisms between these two layers. The results are presented and discussed. This study is replaced within the framework of a chain of modeling of the avalanche phenomenon chronology dealing with the problem since the production conditions to the flow phase.
