Revisiting scale effect on joint roughness coefficient and shear strength considering sampling methods and geometric characteristics

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
The scale effect on shear strength of rock joints is well-documented. However, whether scale effects are negative, positive, or even exist or not is still controversial. Joint roughness significantly influences the shear strength of rock joints. Compared

Determining the surface roughness coefficient by 3D Scanner

open access: yesGeologija, 2010
Currently, several test methods can be used in the laboratory to determine the roughness of rock joint surfaces.However, true roughness can be distorted and underestimated by the differences in the sampling interval of themeasurement methods. Thus, these

On the comparison between the LISFLOOD modelled and the ERS/SCAT derived soil moisture estimates [PDF]

open access: yes, 2008
In order to evaluate the reliability of the soil moisture product obtained by means of the LISFLOOD hydrological model (De Roo et al., 2000), we compare it to soil moisture estimates derived from ERS scatterometer data (Wagner et al., 1999b).

Improvement of rock surface roughness accuracy by combining object space resolution error and 3D point cloud features

open access: yesFrontiers in Earth Science
To enhance the accuracy of joint roughness coefficient (JRC) estimation in photogrammetry, this study employed a fixed-camera shooting strategy guided by a Structure-from-Motion-based shooting parameter selection algorithm to reconstruct 3D models of ...

Shear Behavior of Two-Dimensional Propped Rough Fractures

open access: yesEnergies
The deployment of proppant to fracture shear is a promising approach to stimulating hydraulic permeability in fractured reservoirs. However, the interactive effects of proppant and surface roughness have not been clearly revealed.
