heal.abstract	A simple model is used to derive a formula for the evaluation of the pull out resistance of a symmetric wedge formed in the roof of a circular tunnel which is excavated in a nonhydrostatic stress field. The model assumes two stages of relaxation with different material properties at each stage. Despite its shortcomings, the analysis is useful for parametric evaluation of wedge stability.	en
