Journal ArticleDOI
Ground Response Curves for Rock Tunnels
TL;DR: In this paper, a closed-form solution is presented for an elastic-brittle-plastic material behavior model in which post-peak dilatancy occurs at a constant rate with major principal strain.
Journal ArticleDOI
Estimating the geotechnical properties of heterogeneous rock masses such as flysch
Paul Marinos,Evert Hoek +1 more
TL;DR: In this paper, a methodology for estimating the Geological Strength Index and the rock mass properties for flysch formations is presented, which is used for the design of tunnels and slopes in heterogeneous rock masses.
Journal ArticleDOI
Fracture initiation and propagation in intact rock – A review
Evert Hoek,C.D. Martin +1 more
TL;DR: The Griffith theory of brittle failure provides a simplified model and a useful basis for discussion of this process as mentioned in this paper, and the Hoek-Brown failure criterion provides an acceptable estimate of the peak strength for shear failure but a cutoff has been added for tensile conditions.
Journal ArticleDOI
The Hoek–Brown failure criterion and GSI – 2018 edition
Evert Hoek,Edwin T. Brown +1 more
TL;DR: The Hoek-Brown criterion was introduced in 1980 to provide input for the design of underground excavations in rock as mentioned in this paper, and it has been applied in many projects around the world.
Journal ArticleDOI
The geological strength index: applications and limitations
TL;DR: The geological strength index (GSI) is a system of rock-mass characterization that has been developed in engineering rock mechanics to meet the need for reliable input data, particularly those related to rock mass properties required as inputs into numerical analysis or closed form solutions for designing tunnels, slopes or foundations in rocks as mentioned in this paper.
