Rheological test of soft hard interbedded rock mass

Abstract

The effect of stress level and loading path on rehological behavior of alternating distribution of soft and hard rock layers are investigated with triaxial creep and uniaxial experiments. The results have shown that Different stress states and loading paths have some influence on the rheological behavior of the rock mass. The creep displacement of the rock mass is increased and the lower the confining pressure is, the more obvious the rheological property of the rock mass is, which indicates that the confining pressure has a certain inhibitory effect on the rheology of rock mass.
