摘要：

Within the light of triaxial test results and the so-called <<critical state>> of granular material, we show that the maximum angle of repose of a pile may overpass the angle of friction for initially dense enough materials, but that this leads to a catastrophic event (avalanche). This <<critical state>> approach also allows to relate the mean angle per avalanche to the mean avalanche duration, using an inertial process.
