<p>Although many intact rock types can be very strong, a critical confining pressure can eventually be reached in triaxial testing, such that the Mohr shear strength envelope becomes horizontal. This critical state has recently been better defined, and correct ...

The presentation of the closed-form solution for the problem of the plastic zone and stress distribution around a circular tunnel in an elastic-plastic half space, derived using bipolar coordinates, as well as its implementation in practical examples such ...

This paper presents how to determine equivalent values for the Mohr-Coulomb friction angle φ' and the cohesive strength c' from the tangent to the envelope to the principal stress circles defined by the Hock-Brown criterion.

<p>The Hoek-Brown failure criterion was originally developed for estimating the strengths of hard rock masses. Because of the lack of suitable alternatives, the criterion has been applied to a variety of rock masses including very poor quality rocks, which ...
