| Abstract: | In this paper, the variation of microstructure and the complete process of grain slide during loading of the coral sand are observed with the optical microscope and the self-developed loading device. The statistical calculation of geoxnetric fractal dimension is conducted by the aid of the computer system, and the characteristics of grain slide and fractal dimension variation during loading are obtained. |
