| Abstract: | We develop, in this paper, an analytical approach of continuous medium type which improves the theory of Janssen and other existing approaches of the same type. This approach allows to calculate the stresses in any point of the ensiled granular medium and to represent as well qualitatively as quantitatively the stress saturation effect. The influence of the friction angles is studied. |
