Název v původním jazyce
Model for Granite Fracture Laboratory Tracer Test Evaluation Using the Laser Scanning Data
Popis výsledku v původním jazyce
A model interpreting the laboratory experiment on an artificial fracture in granite block with laser scanning surface data is presented. The aim of the study is to verify whether the hydraulic and migration properties correspond to the general relationships based on the fracture aperture. Laser scanning data of both fracture surfaces are used. Surface scan point cloud with 0.1mm resolution was converted to a regular grid and then interpolated to the numerical discretisation mesh. The primary fracture surface data needed to be corrected by a virtual block movement to get a correct hydraulic aperture. After this change, both the fracture transmissivity and the tracer breakthrough time were fitted with reasonable accuracy, although with several variations up to 40% between the individual tests. Additionally, variants of discretisation and hydrodynamic dispersion were tested.
