Abstract The three-dimensional (3D) morphology of a rock joint has a great impact on its
shear behavior. To study the relationship between the 3D morphological characteristics and …

In this paper, a number of artificial rock specimens with two parallel (stepped and coplanar)
non-persistent joints were subjected to direct shearing. The effects of bridge length (L) …

The asperity morphology has profound influences on the failure characteristics and shear
strength of rock joints. To investigate these influences, degradation characteristics and …

The mobilization of side resistance of rock-socketed pile strongly depends on the shear
behavior of the pile-rock interface. In this study, an asperity-based model was developed to …

Direct shear tests on samples containing similar triangular asperities have been carried out
under constant normal stiffness (CNS) conditions, and observations demonstrated that there …

Anchored bolts are well known as an effective measure to support the rock masses, after all
with stiff steel bolts being inserted into them. Although numerous researches have been …

The time-dependent deformation and long-term strength of rock mass are generally
controlled by the mechanical properties of discontinuity, in particular, creep properties. By …

A hybrid finite-discrete element method was implemented to study the fracture process of
rough rock joints under direct shearing. The hybrid method reproduced the joint shear …

A three-dimensional combined finite-discrete element element method (FDEM), parallelized
by a general-purpose graphic-processing-unit (GPGPU), was applied to identify the fracture …

Quaternary loess is widely distributed over the tertiary Hipparion red clay on the Loess
Plateau of China. Large-scale loess landslides often occur along the weak contact interface …
