RISExperimental and Model Study on the Time-Dependent Permeability of Rock Fractures Induced by Mechanical Creep
Publisher: ASCE
Abstract: Fracture permeability is one of the critical factors affecting thermal production in hot dry rock reservoirs. Mechanical creep can cause temporal reduction of fracture permeability. However, the study solely on mechanical ...
Failure Mode Characteristic of Rocks Containing a Weak Interlayer with Different Thickness and Dip Angles Based on Discrete-Element Method
Publisher: American Society of Civil Engineers
Abstract: Both the integrity and the strength of a rock mass are influenced by weak interlayers. In order to study the failure modes of a rock mass with a weak interlayer under uniaxial compression load, based on the discrete-element ...
Experimental Study on Nonlinear Flow in Granite Tensile and Shear Fractures
Publisher: ASCE
Abstract: Water flow experiments in single tensile and shear granite fractures were conducted to investigate the nonlinear flow behavior. Fracture geometry parameters based on single fracture wall (Rp, Z2, Z3, Z4, JRC) and two ...
