| Abstract: | The value of pore-water pressure and grourd-surface are studied with the fractal geometry theory in this paper. It is observed that the pore-water pressure and ground-surface settlement possess the multi-layered froetal propenties. On the basis of the project the divided-limit is determined. The equation of fractal dimension and the degree of consolidation, the fractal dimension and settling volume have been established. The consolidated deformation of foundation can be forecast by these equations. |
