| 摘 要： | It is well known that the formation permeability is not a constant but a function of the in-situ stress environment. This study has been primarily carried out numerically, and to a certain extent, in the field. However, since the rock properties are generally tested in the laboratory, this last situation needs to be modeled to maintain consistent scales in the analysis. In this paper, concepts and techniques of laboratory experiments are presented to determine relationships between fracture aperture and extemal loading in simulated rocks (concrete).

| Abstract: | It is well known that the formation permeability is not a constant but a function of the in situ stress environment. This study has been primarily carried out numerically, and to a certain extent, in the field. However, since the rock properties are generally tested in the laboratory, this last situation needs to be modeled to maintain consistent scales in the analysis. In this paper, concepts and techniques of laboratory experiments are presented to determine relationships between fracture aperture and external loading in simulated rocks (concrete). |
