Effect of Compaction Banding on the Hydraulic Properties of Porous Rock: Part I—Experimental Investigation
نویسندگان
چکیده
Abstract The mechanical behavior and the influence of compaction banding on hydraulic properties in soft porous rocks were studied. tested rock was Calcarenite Tuffeau de Maastricht. In frame experimental investigations, triaxial oedometric tests conducted under dry drained conditions. results demonstrated that is forming discrete bands high confining stresses steep angle shear low stresses. Permeability measurements during compression conditions axial permeability decreases with increasing strain. maximum decrease three orders magnitude for 40%
