Abstract

The focus of the present paper is on modelling the essential mechanical properties of weathered and partly saturated broken rock using a hypoplastic continuum approach. In particular an increase of the compressibility and a decrease of the limit void ratios with an increase of the moisture content of the solid material is modeled in a simplified manner using only a moisture dependent granular hardness. The constitutive equation for the evolution of the stress is based on nonlinear tensor-valued functions depending on the current void ratio, the stress, a moisture dependent granular hardness and the rate of deformation. It is shown that the results obtained from numerical simulations of element tests are in a good agreement with laboratory experiments.
