The geometric characteristics of fractures within a rock mass can be inferred by the data
sampling from boreholes or exposed surfaces. Recently, the universal elliptical disc (UED) …

Since natural fractures are often non-equidimensional, the circular disc model still has great
limitations. By contrast, the elliptical disc model is more applicable to representing natural …

Abstract The Sichuan-Tibet railway, which spans many alpine canyon regions, is being built
in southwestern China. Investigating the characteristics of rock discontinuity sets is the basis …

Calibration and validation of the Discrete Fracture Network (DFN) model are always based
on the comparison between actual fracture trace map** and cross-section extracted from …

The characterization and clustering of rock discontinuity sets are a crucial and challenging
task in rock mechanics and geotechnical engineering. Over the past few decades, the …

Abstract The Rock Quality Designation (RQD) index is defined as the percentage of the
borehole core or scanline that consists of intact lengths≥ 0.1 m, and has been widely used …

Hydraulic characteristics are important fundamental properties of fractured rock masses and
involve various geoscience and engineering disciplines. The determination of the …

The structural plane characteristic was the most critical factor for determining the self-stability
ability of deep foundation pit vertical-rock-wall in layered rock stratum. Multiple methods …

The representative elementary volume (REV) of a fractured rock mass is crucial for
evaluating the equivalent continuum approach. An innovative computational framework and …

The determination of the representative elementary volume (REV) and equivalent
permeability coefficient (EPC) of fractured rock masses is crucial for studying the hydraulic …
