Solutions are presented for the steady-state, thermomechanical response of an elastic half space containing either a vertical line source or a horizontal disc-shaped source of heat. It is suggested that these solutions may be useful for predicting the long-term behavior of rock masses containing nuclear-waste repositories; the solution for the line source being appropriate for the disposal of hot wastes in deep boreholes and the solution for the disc-shaped source being applicable to disposal in underground galleries of significant lateral extent. It is demonstrated that, in both cases, the surface of the rock mass will heave and that there is potential for cracking of the rock overlying the repositories because of tensile stress changes induced in the region near the surface. Typical values of these quantities were calculated for a rock-mass-like granite.
