| Abstract: | With new developed plane strain apparatus, a series of consolidated undrained plane strain compression tests were carried out on undisturbed clay samples of two main clayey layers. The local deformation of samples was measured and the regularity of localized strain evolution was studied. The study supplied useful information for the research of shear band formation in soil mass. |

| Keywords: | localized deformation plane strain apparatus undisturbed clay sample shear band |
