This paper reports the findings of the Stress and rock mechanics working group of the
Academic Review of Hot Dry Rock/Hot Wet Rock (HDR/HWR) Engineered Geothermal …

This paper describes the solution of the plane strain problem of a hydraulic fracture
propagating in a permeable, linear elastic medium. The fracture propagation is driven by …

We subjected boreholes drilled vertically in the center of cubical specimens of Lac du
Bonnet granite to constant vertical (S v) and least horizontal (S h) farfield stresses, and …

Hydraulic fracturing is one of the best-known methods of in situ stress measurement at great
depths. In the last two decades, this method has been used as an important tool for pre …

In this paper, the estimation of boundary conditions for rock mass models is addressed by
means of Bayesian identification procedures. Basic information can consist of stress, strain …

Deep in situ rock stress determinations are typically conducted using hydraulic fracturing in
an existing borehole or by applying specialized overcoring techniques that require the …

A project to develop an excavation design process for potential application in construction of
a nuclear fuel waste repository was undertaken in Canada at the Underground Research …

Convergence measurements were taken during the construction of a circular shaft in
massive granite. The convergence results were used to back-calculate the in situ horizontal …

High and deviatoric sub-horizontal stresses, geological structures and variable strengths for
the greenstone rocks combine to make Western Australia's Yilgarn Craton one of the most …
