Shearing tests with continuously increasing normal stress

open access: yes, 2006
In the conventional shearing tests the normal force or the normal stiffness are kept constant during the experiment. Sliding under constant normal load occurs in slopes if the environment is not changing during the process.

The prediction and back analysis of excavation behaviour in Oxford Clay. [PDF]

open access: yes, 1996
The work described in this thesis involved the prediction and back-analysis of ground movements and pore water pressures around a temporary excavation, lOm deep, 105m long and 35m wide (50m long and lOm wide at its base) in the heavily overconsolidated

Limiting envelopes of a porous limestone under true triaxial stress states

open access: yes, 2010
The influence of the intermediate principal stress on the failure mode and the mechanical behaviour of a porous limestone is investigated by means of true triaxial tests conducted on dry rock samples. The experimental conditions range from triaxial (s2 =

Strength characteristics and shear acoustic anisotropy of rock core subjected to true triaxial compression

open access: yes, 1995
Results are presented from an initial experimental programme aimed towards evaluating the capabilities of a new true triaxial cell, designed to apply independent and unequal principal stresses to the curved surfaces of cylindrical core plugs. A series of
