Measurement of Rock Joint Surfaces by Using Smartphone Structure from Motion (SfM) Photogrammetry [PDF]
Sensors, 2021 The measurement of rock joint surfaces is essential for the estimation of the shear strength of the rock discontinuities in rock engineering. Commonly used techniques for the acquisition of the morphology of the surfaces, such as profilometers and laser ...

Damage law and mechanism of coal-rock joint structure induced by liquid nitrogen at low temperature [PDF]
Scientific Reports, 2022 The width and degree of connectivity of coal-rock joints directly affect the seepage capacity of flow energy such as gas. To study the damage law and mechanism of the coal-rock joint structure under the action of liquid nitrogen, two methods of liquid ...

Composite filter-based detection of rock joints from drilling parameters [PDF]
Scientific ReportsIn geotechnical engineering, rock joints are the key factor in determining the stability of rock. Quickly and accurately identifying the joints in the rock has always been a concern in geotechnical research. A drilling experiment was designed for jointed

MATHEMATICAL DETERMINATION OF ROCK JOINTS MORPHOLOGICAL PROFILE
Rudarsko-geološko-naftni Zbornik, 2022 Determining the geometric or morphology and mechanical properties of joints and geomechanics of intact rock is a vitally important issue in predicting the behaviour of structures built inside or on rock masses. The joint morphology is significant because

Seismic response of rock joints and jointed rock mass [PDF]
, 1996 Long-term stability of emplacement drifts and potential near-field fluid flow resulting from coupled effects are among the concerns for safe disposal of high-level nuclear waste (HLW). A number of factors can induce drift instability or change the near-field flow patterns.
