Slope stability analysis: Barodesy vs linear elastic – perfectly plastic models [PDF]
E3S Web of Conferences, 2019 The results of slope stability analysis are not unique. Different factors of safety are obtained investigating the same slope. The differences result from different constitutive models including different failure surfaces. In this contribution, different

Determination of Equivalent Mohr-Coulomb Criterion from Generalised Hoek-Brown Criterion [PDF]
, 2021 Abstract A new analytical solution is presented for determining equivalent Mohr-Coulomb (MC) shear strength parameters over an arbitrary interval of minor principal stress σ3 from the generalised Hoek-Brown (HB) criterion using least squares method.

A Three-Dimensional Elastoplastic Constitutive Model for Geomaterials
Applied Sciences, 2023 The Mohr-Coulomb (M-C) failure criterion has been a popular choice for geotechnical analysis because of its simplicity and ease of use. The fact that the M-C criterion disregards the intermediate principal stress’s impact is a significant drawback.

A New Unified Solution for Deep Tunnels in Water-Rich Areas considering Pore Water Pressure
Geofluids, 2021 Pore water pressure has an important influence on the stresses and deformation of the surrounding rock of deep tunnels in water-rich areas. In this study, a mechanical model for deep tunnels subjected to a nonuniform stress field in water-rich areas is ...
