英文摘要 | A test apparatus was developed to study shear-flow coupling properties for a marble fracture with sand. Experimental tests include shear stress-flow coupling process and shear displacement-flow coupling process. The shear stress-flow coupling test results, revealed that mechanical aperture keeps constant during shear, and that hydraulic aperture and conductivity decrease almost linearly with increasing shear stress. The shear displacement-flow coupling test results showed that hydraulic behavior under shear displacement includes two phases. During the first about 0.05mm shear displacement, hydraulic aperture and conductivity decrease with increasing shear displacement, and mechanical aperture remains constant or increases only by several microns of magnitude. After shear displacement is up to about 0.05mm, the fracture dilates remarkably, and hydraulic aperture and conductivity increase with shear displacement increasing. |
