Influences of principal stress direction and intermediate principal stress on the stress–strain–strength behaviour of completely decomposed granite

Canadian Geotechnical Journal, 2010
The measurement and study of the stress–strain–strength behaviour of soils in general stress states involving the change of magnitudes and direction of the principal stresses are necessary and important. To investigate the strength behaviour under such conditions, consolidated undrained tests on remoulded hollow cylinder specimens of completely ...

Effect of intermediate principal stress on the deformation response of sand

Canadian Geotechnical Journal, 1996
An experimental investigation of the relevance of the intermediate principal stress (σ2) on the deformation response of a sand is presented. The effects of σ2 are conveniently studied through the nondimensional stress parameter b = (σ2 – σ3)/(σ1 – σ3).

Effects of intermediate principal stress on rock cavity stability

Journal of Central South University of Technology, 2007
The linear Mohr-Coulomb and nonlinear Hoek-Brown failure criteria, which neglect the effects of intermediate principal stress, are widely used in soil and rock engineering. However, much experimental data shows that the failure envelope relates to the intermediate principal stress.

Experimental Study on Influence of Intermediate Principal Stress on the Permeability of Sandstone

Transport in Porous Media, 2020
In engineering, it is considerably important to understand the evolution process of sandstone deformation and permeability under complex stress conditions. Although numerous scholars have reported on sandstone permeability, many of their studies are only based on uniaxial or conventional triaxial stress conditions.

Effects of intermediate principal stress on tensile strength of rocks

International Journal of Fracture, 2013
The objective of this study is to experimentally determine the effects of intermediate principal stresses on the tensile strength of rocks. The results are used to assess the predictive capability of the Coulomb criterion when one or more principal stresses are in tension. Four rock types have been tested.

Effect of Intermediate Principal Stress on Overconsolidated Kaolin Clay

Journal of Geotechnical and Geoenvironmental Engineering, 2004
The influence of intermediate principal stress on the mechanical behavior of overconsolidated kaolin clay is investigated using three-dimensional true triaxial testing on cubical specimens. A flexible boundary, true triaxial setup with a real-time feedback control system was used to test soil specimens under stress and strain-control modes.

Effect of the intermediate principal stress on rock failure

Journal of Geophysical Research, 1967
Precise testing methods have been applied to an experimental study of the effect of the intermediate principal stress σ2 on failure of a granite, a limestone, and a dolomite rock at room temperature. σ2 affects failure in two ways. Strength at failure increases with σ2 by an amount that is proportional to, although smaller than, the amount of the least

Effects of Cyclic Rotation of Principal Stress Axes and Intermediate Principal Stress Parameter on the Deformation Behavior of Sands

Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008
Four series of drained tests on sands were performed with a hollow cylinder apparatus in order to investigate the fundamental deformation behavior of sands and the effects of the intermediate principal stress parameter b during cyclic rotation of principal stress axes.

Influence of intermediate principal stress on the fault strength

Physics of Fluids
Earthquake risk assessment of fault often overlooks the influence of intermediate principal stress (σ2) on fault. However, recent studies have shown that σ2 can alter the internal friction angle, which in turn affects the friction coefficient and strength of rock.
