Abstract

A general verification of the Janssen model was carried out by measuring the bottom pressure of different granular materials confined in a cylindrical column. Special effort was made in order to experimentally test all the physical parameters appearing in Janssen's equation, especially the particle-wall friction coefficient μ and Janssen's factor, K. The results indicate that although Janssen's approach is capable of qualitatively reproduce the observed behavior, the physical meaning of the parameter appearing in Janssen's equation requires further considerations.
