摘　　要：从土体的微结构出发,运用分形几何的理论,计算土体微结构状态的分维指标.并把计算所得的分形维数与土体的龄期相联系,得到他们之间的定量数学表示关系,给出一个判断土体强度的新方法,从而推动土力学的发展.In this paper, the fractal dimension 'D' of the soil microstructure was computed by using fractal theory. By connecting dimension 'D' with soil age, mathematical quantitative relation of them was obtained, so and a new way of judging soil strength was found, which will contribute to the progress of soil mechanics.
