Methods of in situ Stress Measurement

1997
Compared with other rock mass properties, rock stress is a difficult quantity to measure. As pointed out by Leeman (1959), ‘It is impossible to measure stress directly since, in fact, it is a fictitious quantity. It is only possible to deduce the stresses in a solid body from the results of measurements using some indirect method’.

In Situ Stress Measurements in Austria

1980
In situ stress measurements were made at 6 locations in Austria, which were chosen in such a fashion as to yield information on the neotectonic stress in the country. Because of a strong influence of the Alpine topography, it was necessary to apply finite-element calculations for the interpretation of the field results.

Analysis and modelling of holographic measurements of In Situ stress

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1988
Holographic in situ stress measurements were made at five azimuths at a single depth in a horizontal borehole in a mine pillar. For the first time, all six components of the stress tensor were determined by this technique. The stressmeter data indicate a vertical stress of −10.2MPa (compressive), in good agreement with the predicted vertical stress for

Hydraulic fracturing for in situ stress measurement

Journal of Mining Science, 2016
It is experimentally found that shut-in pressure conforms with the fracture initiation pressure if the fracture surfaces are uniformly loaded by fluid. The article shows that equaling minimal stress and shut-in pressure in local fractures results in overestimates.
