Dynamic micro-CT analysis of fracture formation in rock specimens subjected to multi-phase fluid flow [PDF]

open access: yes, 2015
In this study, fracture formation in rocks is being studied at the pore-scale through the combination of high-resolution X-ray CT scanning with custom-made add-on modules.

Determining the REV for Fracture Rock Mass Based on Seepage Theory

open access: yesGeofluids, 2017
Seepage problems of the fractured rock mass have always been a heated topic within hydrogeology and engineering geology. The equivalent porous medium model method is the main method in the study of the seepage of the fractured rock mass and its ...
