Effects of intermediate principal stress on rock cavity stability
Journal of Central South University of Technology, 2007The 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.

Effect of Intermediate Principal Stress on Overconsolidated Kaolin Clay
Journal of Geotechnical and Geoenvironmental Engineering, 2004The 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.

Influence of intermediate principal stress on the fault strength
Physics of FluidsEarthquake 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.

Effect of the intermediate principal stress on rock failure
Journal of Geophysical Research, 1967Precise 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

Effect of intermediate principal stress on strength of anisotropic rock mass
Tunnelling and Underground Space Technology, 1998Abstract The Mohr-Coulomb criterion needs to be modified for highly anisotropic rock material and jointed rock masses. Taking σ2 into account, a new strength criterion is suggested because both σ2 and σ3 would contribute to the normal stress on the existing plane of weakness.

Influence of Intermediate Principal Stress Effect on Flat Punch Problems
Key Engineering Materials, 2013Using the finite difference code FLAC3D (Fast Lagrangian Analysis of Continua in 3 Dimensions) and UST (Unified Strength Theory), the influence of the intermediate principal stress effect on the problems of flat punch are analyzed in this paper. The values of the ultimate bearing capacity resulting from numerical analyses and the analytical solution of ...

Abstract In this paper, the Discrete Element Method (DEM) is employed to numerically explore the response of hollow cylinder specimens of granular soils under complex stress paths. Two series of numerical tests are conducted to clarify the effects of the principal stress direction α and the intermediate principal stress through the b-value on the ...
