DECOVALEX I - Test Case 2: Calculation of the Fanay-Augeres THM Test -Thermomechanical modelling of a fractured rock volume
A large scale thermo-mechanical test in the French uranium mine Fanay-Augeres at the depth of 100 m has been simulated with the finite element code ABAQUS. The calculations have been compared with measurements of rock displacements. The calculations included excavation of the test room and the heating and cooling periods of the test. The rock has been modelled both as linear elastic and as fractured with elastic-plastic properties of the fractures. A sensitivity analysis of factors influencing the results were made with elastic calculations. It showed that the boundary conditions and the properties of the surrounding rock had no influence on the effect of the heating but a substantial influence on the effect of the excavation. Comparisons between calculated and measured results of the heating and cooling test showed that the introduction of fractures did not yield more accurate results than those obtained with the fracture free linear elastic model. 3 refs, 60 figs, 13 tabs.
