Thermo-mechanical coupling analysis for DECOVALEX-2011 Task B, Äspö pillar stability experiment
Korea participated in DECOVALEX-2011, which is an international cooperation project for enhancing the reliability of computer simulations under the conditions of radioactive waste repositories, and modeled the laboratory compression tests and the in situ Äspö pillar stability experiment (APSE). From the comparison of the results with foreign research teams, it was possible to enhance the reliability of the computer simulation of the complex thermo-mechanical (TM) coupling behavior of rock mass. It was found that the two-step simulation with a full model and a submodel using FLAC3D was effective to combine the influence of in situ stress, tunnel excavation, deposition hole drilling, confining pressure, and thermal loading all together. One of the important results was the estimation of spalling strength of Äspö granite as 120 MPa after comparing the notch depth, notch length, and breakout angle of the notch with actual observation.
