Abstract EN
The property of water flow through a single rock fracture is the base of describing the seepage characteristics of jointed rock mass.
Five artificial tensile fractures of coarse-grained cylinder marble samples were made at about the midpoint of the long axis by using a self-made splitting mold.
The upper and lower surfaces of the tensile fractures were scanned by a 3D laser scanner (OKIO) to obtain their 3D coordinates.
Then, the Geomagic Studio Software and rock surface topography scan test software were used to obtain peak density values of each single fracture surface.
To study the seepage characteristics of open fracture, 4 rectangular plastic spacers with the size of about 3 mm × 2 mm × 0.2 mm were put into the fracture when water flowed through the single rough fracture tests were conducted under different normal stresses using the self-developed radial flow system.
According to the testing data, the relationships between the seepage characteristics of single rough rock fracture and the peak density of fracture surface were studied.
It is discovered that the 3D fracture morphology had great influences on the seepage characteristics of the single rock fracture.
A modified cubic law was put forward to present the relationship between the seepage characteristics of a rough rock fracture and peak density of two fracture surfaces.
Comparison between the modified cubic law and the experimental data showed a relatively good agreement.
