Study on Interfacial Crack Initiation of Jointed Rock Mass Based on Interface Fracture Mechanics

open access: yesFractal and Fractional, 2022
The fracture of interfacial crack is the main failure type of jointed rock mass. Therefore, it is very important to study the interfacial fracture of jointed rock mass. For the similarity of jointed rock mass and composites (all are composed by two parts,

Study on the constitutive model for jointed rock mass. [PDF]

open access: yesPLoS One, 2015
A new elasto-plastic constitutive model for jointed rock mass, which can consider the persistence ratio in different visual angle and anisotropic increase of plastic strain, is proposed. The proposed the yield strength criterion, which is anisotropic, is not only related to friction angle and cohesion of jointed rock masses at the visual angle but also

Seismic response of rock joints and jointed rock mass [PDF]

open access: yes, 1996
Long-term stability of emplacement drifts and potential near-field fluid flow resulting from coupled effects are among the concerns for safe disposal of high-level nuclear waste (HLW). A number of factors can induce drift instability or change the near-field flow patterns.
