The stress and time dependent behaviour of soft rocks

Zvonko Tomanović

Abstract

In mathematical description of time dependent behaviour of a material, the basic task is to define deformations as a function of time, stress, and temperature. The influence of stress state on deformation response of the rock mass has been experimentally determined on uniaxial, bi-axial and three-axial specimens of marl by short loading, and by creep tests in the period from 3 to 360 days. The suggested model may be applied for description of time dependent deformations under full constant load, but also after the total or partial unloading, which is significant for the stress condition in the rock mass around the tunnel opening.
