In this paper, a digital image analysis method is described to observe the deformations of granular particles insands. First, the movements of granular particles in sands were observed as the image data during the direct sheartest of Toyoura sand. And the strains in global scales were calculated continuously by the analysis of the relativemovements of adjacent individual particles.As the result, the shear zone can be determined clearly by the above strain distributions. Furthermore, the con-ducted dilatancy angle in this study was nearly closed to the value in the previous paper.
