Determining the in situ state in volume of interest

Stress characterisation is important to design and critical decision making. Uniformity in the in situ stress state of rock mass is rare; its distribution depends largely on geological structure and loading history. A successful measurement campaign is not limited to acquiring point measurements but also must include a prudent examination and integration of available data, observations, and relevant site information. This talk will cover a brieft review of the most common field measurements employed in practice, including those used by MIRARCO's Geomechanics Research Centre, and the approach used to ascertain a best approximation in addition to highlighting the challenges faced.
