Journal ArticleDOI
Investigation on the Water Flow Evolution in a Filled Fracture under Seepage-Induced Erosion
TL;DR: In this article, a numerical model for the evolution of flow in a filled fracture under seepage-induced erosion was established, which included the flow velocity, hydraulic erosion, and the permeability of the filling medium.
Journal ArticleDOI
An enhanced index for evaluating natural joint roughness considering multiple morphological factors affecting the shear behavior
TL;DR: Wang et al. as mentioned in this paper proposed a new index named shear roughness coefficient (SRC) to accurately estimate the shear strength of rock joints, which can be extended from 2D to 3D surface of natural joint.
Journal ArticleDOI
Method Comparison to Determine Hydraulic Apertures of Natural Fractures
TL;DR: Hale et al. as discussed by the authors used a syringe air permeameter, a microscope camera and a 3D laser scanner in combination with an articulated arm to determine hydraulic apertures of a Permian sandstone.
Journal ArticleDOI
Empirical Shear Strength Criterion for Rock Joints Based on Joint Surface Degradation Characteristics During Shearing
TL;DR: Wang et al. as discussed by the authors used regression analysis to evaluate the JRC values of rock joints under various displacements, and a new empirical equation was introduced to predict peak shear displacement.
Journal ArticleDOI
The Effect of Asperity Inclination and Orientation on the Shear Behavior of Rock Joints
TL;DR: In this article, the effect of asperity inclination angle and inclination angle on the shear behavior of rock joints under constant normal loading conditions was investigated by creating artificial rock joints having a regular pattern of triangular asperities that were oriented at different angles in the plane of shear.
