RECENT ADVANCES IN THE INTERPRETATION OF THE FLAT JACK TEST

The use of the flat jack test to identify the residual strength of rock masses is discussed. Test interpretation procedures developed by means of numerical models of the slot are presented. The same procedures are applicable to the determination of original stresses as an alternative to the "cancellation pressure" method recommended by irsm suggested standards. The use of the flat jack for deformability measurements is also analysed and the limitations of the conventional interpretation formula are outlined. The number of the covering abstract of the congress is TRIS no. 385148. (TRRL)
