Rock fragmentation by blasting is still among the most challenging of problems in
geomechanical engineering. The intent of this work is not to develop a new overall blast …

Bedding-perpendicular joints (BPJs) in soft-hard interbedded masses exhibit heterogeneous
distribution. Statistical analysis revealed the impacts of interface morphology on the …

The impact-induced rock mass fragmentation in a rockfall is analyzed by comparing the in
situ block size distribution (IBSD) of the rock mass detached from the cliff face and the …

Rock engineering in blocky rock masses demands a sound knowledge about the joint
network, since it consists of planes of weakness than can lead to block instabilities …

Nearly 3,600 vertical joints were measured in sand-mud interbedded rock masses from 30
outcrops in the Yan'an area, China. Information such as joint spacing, joint aperture and the …

The present article reviews various methods for discontinuity and rock block survey. The
variety of techniques to determine the shape and size distribution of the rock blocks were …

The representative elementary volume (REV) is the premise of the continuous-media
method of analysis, and the investigation of the REVs of fractured rock masses is a …

Fracture spacing (s) distribution and its dependence on bed thickness (t) are investigated for
opening-mode joints in sandstone interlayered with shale in the Sainte-Anne des Monts …

When studying rockfall phenomena, a single value of the block volume is not sufficient to
take into account the natural variability of the geometrical features (orientation, spacing …

Block size and shape depend on the state of fracturing of the rock mass and, consequently,
on the geometrical features of the discontinuity sets (mainly orientation, spacing, and …
