The results of two‐dimensional finite element analyses of several thermal/mechanical loading cycles of the G‐Tunnel heated block experiment are presented. The deformations of the block resulting from thermal loading under constant biaxial stress were determined using a recently developed compliant‐joint rock‐mass model. The results of the finite element calculations were compared to experimental results reported by Zimmerman et al. Qualitative agreements between the experimental and numerical results were obtained in all cases while quantitative agreements were achieved in some cases. The results of this evaluation are discussed.
