Numerical back analysis is a valuable tool available to rock mechanics researchers and
practitioners. Recent studies related to back analysis methods focused primarily on …

Rock properties are estimated using objective lab/in-situ testing and subjective judgements
invoking different types of uncertainties, ie, aleatory, and epistemic, along them, often …

The magnitude and direction of stress will affect the failure of roadway. The impact of stress
magnitude and direction on roadway failure was investigated using a rock failure system …

Abstract Changes of failure mechanism with increasing confinement, from extensional to
shear-dominated failure, are widely observed in the rupture of intact specimens at the …

Brittleness is an important property of rocks in the context of engineering applications, as it
often determines how severe the practical consequences of rock yield will be. Many authors …

Within a well-established stress environment and with well-established laboratory
properties, Hawkesbury Sandstone in the Sydney region of Australia hosts, and will continue …

Abstract In this study, Bonded Block Models (BBMs) are used to investigate the pillar
damage mechanisms and rock-support interaction in massive-to-sparsely-fractured …

Underground infrastructures are crucial for resource extraction, energy storage, and space
utilisation. The geomaterials that make up these structures, such as rock and concrete, are …

When carrying out compressive tests on rock specimens, a stress plateau is typically
attained following peak strength within a strain range a few times larger than the strain at …

Excavation-induced unloading fractures in the rock mass can easily cause rock engineering
structural failure under high stress. This research work investigated the unloading fracture …
