Laboratorní stanovení hydrodynamických a migračních parametrů granitových bloků a jejich vztah k šíření seismických vln - informace o řešení projektu

Abstract

Hydrodynamic and migration parameters of granite blocks are very important features on research of efficiency of injection grouts used in a fracture systems of granite. In this paper we discus an influence of hydraulic gradient on the volumetric flow through the media and diffusion of chemical tracers at natural and artificial fractures. We also provided some tests of ultrasound velocity at fractured and solid rock. Our results correspond to our theoretical presumptions – the higher pressure of water causes lower diffusion than lower pressure and fractured granite has lower velocity of ultrasound waves than solid one.
