Close
- deformation gauge, the C.S.I.R.O. hollow inclusion stress cell, the cast epoxy inclusion, the Lulea triaxial strain cell, and the C.S.I.R. doorstopper'' gauge to assess the suitability of each technique for in situ stress determination in a closely jointed basalt. This effort is in support of the Basalt Waste Isolation Project which is studying the feasibility of locating a nuclear waste repository in basalt. Testing at the NSTF provided information for the evaluation of overcoring techniques so that one or more can be selected to obtain in situ stress data at the reference repository horizon. Even though some problems were experienced, the borehole deformation gauge and doorstopper proved the most successful. 30 refs., 53 figs. 16 tabs.
