Unloading Effect

The stability of a rock wedge resting on two intersecting discontinuities is examined under excavation unloading forces. The variation of the factor of safety as well as the external force required to restore a certain factor of safety is examined for a range of values of ambient stress coefficient and for a variation in the distance of a crack from the cut face of the wedge.
