Three-Dimensional Joint/Interface Element for Rough Undulating Major Discontinuities in Rock Masses

Constitutive model for rock fractures: Revisiting Barton's empirical model

“…to simulate the observed behavior; (b) the empirical approach, in which physical data are analyzed to derive correlations between variables of influence and models are formulated according to observed behavior. Several empirical and theoretical constitutive models were developed by Patton (1966a), Ladanyi and Archambault (1969), Barton (1971), Goodman (1974Goodman ( , 1976, Barton and Choubey (1977), Hsu-Sun (1979), Bandis et al (1981), Swan (1981), Heuze and Barbour (1981), Barton et al (1985), Pande (1985), Kane and Drumm (1987), Plesha (1987), Fishman (1987, 1991), Amadei and Saeb (1990), Gens et al (1990), Jing (1990), Jing et al (1993), Qiu et al (1993), Huang et al (1993), Wibowo et al (1993), Wibowo, (1994), Kana et al (1996), Fox et al (1998), Wang et al (2003), Samadhiya et al (2008), etc.…”

Shear strength of discontinuities in sedimentary rock masses based on direct shear tests

“…to simulate the observed behavior of a discontinuity; and (b) the empirical approach, in which experimental data are analyzed to derive correlations between influential variables, and models are formulated according to the observed behavior. To date, several empirical and theoretical models have been developed to predict the shear strength of discontinuities in rock masses, such as Patton [1,2], Goodman [3,4], Jaeger [5], Barton [6][7][8][9][10], Jing et al [11], Grassellia and Egger [12], Samadhiya et al [13], Asadollahi and Tonon [14], Tang et al [15], etc. Asperity degradation of rock discontinuities has been carried out by Ladanyi and Archambault [16], Hutson and Dowding [17], and Lee et al [18].…”

Importance of Tensile Strength on the Shear Behavior of Discontinuities

“…Several researchers, such as Patton (1966), Ladanyi and Archambault (1970), Barton and Choubey (1977), Plesha (1987), Saeb and Amadei (1992), Maksimović (1996), KaÑ a et al (1996), Fox et al (1998), Amadei et al (1998), Wang et al (2003), Grasselli and Egger (2003), Samadhiya et al (2008), and Asadollahi and Tonon (2010), have estimated the shear strength of a rough rock joint. These criteria have been proposed for discontinuities with identical joint wall compressive strengths (DIJCS) under CNL conditions.…”
