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 …

More often than not, it is difficult or even impossible to obtain directly the specific rock
parameters of interest using in situ methods. The procedures for measuring most rock …

Rock mass quality evaluation is a challenging task in geotechnical investigations given the
natural heterogeneity and the limited data. These investigations mainly depend on the …

Abstract Characterization of rock masses and evaluation of their mechanical properties are
important and challenging tasks in rock mechanics and rock engineering. Since in many …

Bedrock fracturing and rock strength are widely believed to influence landscape morphology
and erosional resistance. Yet, understanding of the quantitative relationship between rock …

Refraction seismics is a common geophysical application to investigate permafrost in alpine
studies. This study reviews the physical basis of the use of refractions seismics and …

Rock quality designation (RQD) is a critical geoengineering/geotechnical parameter for
evaluating rock mass quality (RMQ), which is a preliminary construction decision-making …

The role of bedrock fractures and rock mass strength is often considered a primary influence
on the efficiency of surface processes and the morphology of landscapes. Quantifying …

Accurate evaluation of rock mass quality and faults/fractures is the main challenge in rock
mechanics and rock engineering. Rock quality designation (RQD) is an important rock mass …

Uncertainty in geological models, mainly caused by natural heterogeneity and inadequate
data, often leads to substantial societal risk including failures of engineered structures …
