A rheological model of the behaviour of rocks and rock masses

Abstract

This work presents rheological models of fissure closure body, creep body, yielding body and one body that are representative of rocks and rock masses, their rheologic equations, and their behaviour in creep and under constant load velocity. Lastly results of tests on two specimens of different rocks are given, and values of their rheologic constants are determined as well as deviation of unit strains calculated with reference to those measured.
