“…The plastic zone radii calculated by associated flow rule and nonassociated flow rule are almost consistent. However, the radial displacement of rock mass increases 10.64% (e-p model), 11.84% ( = 0.04), 13.91 ( = 0.006), and 14.13% (e-b-p model) if it adopted associated flow rule. Obviously, with the continuous deteriorations of strength parameters, the result differences between associated flow rule and nonassociated flow rule will increase gradually.…”

“…In particular, it is pointed out that the case of stress exchange can occur in the calculation. Wang et al [11] improved Reed's approach and presented an analytical solution of surrounding rock under different axial stresses which is based on Mohr-Coulomb 2 Mathematical Problems in Engineering failure criterion. Particularly, the stress and displacement of surrounding rock under three different axial stress states were discussed in his paper.…”

“…For nonplane problems, Lu et al [21] presented the elastoplastic solutions for a circular tunnel with considering the axial stress, showing that the distributions of plastic zones are dependent on the axial and horizontal in situ stresses. Wang et al [22] suggested an elastic-brittle-plastic constitutive model with a nonassociated flow rule.…”

“…Lu et al (2010) and Zhou and Li (2011) studied the effects of the out-of-plane stress and ground stress on rock stress, displacement, and strain variations. Although Wang et al (2012) considered the influence of plane stress on rock stress, strain, and displacement distribution on the basis of plane strain, they did not consider the impact of penetration.…”
