Development of deep-underground engineering structures via 2D and 3D RQD prediction using non-invasive CSAMT. [PDF]

open access: yesSci Rep
The stability criterion based on the characterization of rock masses can be used to advance deep underground engineering projects. A key geomechanical criterion in geotechnical engineering is rock quality designation (RQD), which assesses risk for engineering design success criteria.

Deep Underground Engineering and The Use of Artificial Intelligence Techniques [PDF]

open access: yesInternational Journal of Earth & Environmental Sciences, 2018
The use of underground space for engineering systems has been increasing worldwide. Underground geoengineering is characterized by complex, uncertain geology and geomechanics that present challenges and require new tecniques to be dealt with. These challenges include large overburden which cause high stresses and temperatures, that require complicated ...
