Abstract

Creep in rock masses is typically described as the gradual deformation that occurs when loads are applied for long durations at varying temperatures. This process, which may result from chemical reactions in susceptible environments, leads to instabilities and catastrophic strength degradation in the rock masses. An example of a susceptible environment is crystalline and sedimentary host rocks or rock salts in deep geological repositories. Such environments are subject to the long-term transfer of radionuclides at high temperatures. This research is focused on the study of creep in several numerical examples under different loading conditions. The simulations are conducted using finite element analysis of viscoelastic and viscoelastoplastic materials. The former uses the known Waste Isolation Pilot Plant (WIPP) model, and the latter incorporates a newly proposed viscoelastoplastic model that integrates the WIPP and Mohr-Coulomb (MC) models. Results are verified with available closed-form and numerical solutions.
