Relationship between the isotropic collapse pressure and the uniaxial compressive strength, and depth of collapse, both derived from a new failure criterion for low density pyroclasts

ABSTRACT

A theoretical relationship between the isotropic collapse pressure and the uniaxial compressive strength is obtained for low density pyroclasts, based on a failure criterion proposed by the authors, and it is compared to empirical results. Also based on the proposed failure criterion, a theoretical collapsed depth of ground has been deduced, due to the internal stresses overcoming the failure criterion of the material.
