Abstract: This paper deals with a spherical cavity excavated in infinite homogeneous and isotropic strain-softening rock mass subjected to a hydrostatic initial Displacements and stresses distributions are two of the most important information for underground engineering, for that it can provide a theoretical foundation for geotechnical engineering optimism design and stability evaluation. In past few years, many scholars have developed series of (semi-)analytical and numerical solutions for circular openings and spheri… Show more

“…Adopting the M-C criterion and nonassociated flow rule and introducing the large deformation theory, Wang and Zhu [22] obtained an elastoplastic analytical solution to the cavity expansion. Zhang et al [23] established a multistep brittle-plastic model by simplifying the strain-softening process of the postfailure region, and they proposed analytical solutions of a spherical cavern with considering the deterioration of elastic parameters. Both M-C and H-B criteria are included in their analysis.…”
