Geological and geotechnical characterization of Ntambeng basalt massif used as aggregates in civil engineering (North-West Cameroon)

Discover Geoscience
Basalt massif outcrops in Ntambeng. Construction companies used these rocks extensively for various purposes such as structural loading, pavements, and wall cladding. This study aims to characterize both geological and geotechnical points of the Ntambeng

Modeling Brittle-to-Ductile Transitions in Rock Masses: Integrating the Geological Strength Index with the Hoek–Brown Criterion

Applied Mechanics
Many studies focus on brittle–ductile transition stress in intact rocks; however, in real life, we deal with rock mass which contains many discontinuities.

Method for evaluation of geological strength index of carbonate cliff rocks: Coupled hyperspectral-digital borehole image technique

Journal of Rock Mechanics and Geotechnical Engineering
The deterioration of unstable rock mass raised interest in evaluating rock mass quality. However, the traditional evaluation method for the geological strength index (GSI) primarily emphasizes the rock structure and characteristics of discontinuities. It
