Plasticity models employing multiple yield surfaces are frequently met in plasticity theory and
engineering practice. The multiple yield surfaces may or may not intersect in a smooth …

Preventing roof collapse in underground cavities is a challenge to geotechnical engineering.
In this study, three independent methods have been used to evaluate the roof collapse of …

Reliably estimating the mechanical properties of discontinuous rock masses remains one of
the greatest challenges faced in the discipline of rock mechanics. This paper discusses the …

This paper investigates the roof collapse of deep circular cavities in jointed rock masses
using adaptive finite element limit analysis. The rock mass strength is described by the …

The elastic perfect plastic model (EPP) fails to accurately capture the strain-softening
mechanical behaviors of rock masses, while the post-peak constitutive model of elastic …

The lower-bound finite elements limit analysis in combination with semidefinite
programming (SDP) has been used to solve stability problems involving a modified Hoek …

A basic step in the design process of footings is to assess the bearing capacity. For many
years this was done exclusively based on the Mohr–Coulomb material model. But since the …

Abstract The Generalized Zhang and Zhu (GZZ) strength criterion is one of the three-
dimensional criteria suggested by the International Society for Rock Mechanics and Rock …

Excavation within high-stress brittle rock masses often encounters severe problem of
structural damage in deep underground engineering, necessitating a significant scientific …

The composite lining load of a deep-buried tunnel is one of the key problems in tunnel
support design. This study establishes four support cases to discuss the loads on primary …
