Experimental Study of Compaction Bands in Diatomaceous Porous Rock
To observe the strain localization of both shear and compaction bands, a series of triaxial compression tests under the drained condition was performed on diatomaceous porous rock. A rectangular‐shaped prismatic specimen was used to easily measure the strain distributions on the specimen surface. The distributions of local strain, i.e., shear strain, axial strain, and volumetric strain, were measured on the surface of the specimen by using an image analysis technique newly developed for this experiment. After the shear testing, the changes in density of the specimen were measured by an X‐ray CT scanner. Some high density regions were found to correspond to the compaction bands observed in the image analysis in the cases of relatively high confining pressure levels.
