RESIDUAL STRESS FIELD IN ROCK

RESIDUALSPENNINGER I FJELL

Changes in the residual stress field in rocks can be measured indirectly by recording changes in sonic pulse travel time and the point load index. The methods are quantitative as well as qualitative and are suitable for giving a practical measure of the energy dissipation properties of rock materials. Changes in the residual stress fields have practical consequences for the long term stability of underground openings and for the mechanical properties of rock materials in general. (a) (TRRL)
