| Summary: | 碩士 === 國立屏東科技大學 === 土木工程系所 === 101 === The soil physical properties depend on the size distribution and arrangement of the soil particles. Soil system includes solid, water and air phases. The interactive of phases affect the moisture transport and soil mechanics. As a matter of fact, the soil structure and texture are difficult to detail description through soil physical testing. In this paper, the box-counting dimension of fractal method used to calculate the soil particles distribution dimension. The result shows that the fractal dimension method can use as an index to descript the soil particles distribution property. The analog about spatial entities for numerical simulation to fractal dimension variation of different partical arrangement, explore its relationship between that and characteristic length for hydraulic conductivity. The results showed the significantly negative correlation between fractal dimension and soil porosity and the negative correlation between fractal dimension and hydraulic conductivity of the modeling experiment with reverse inference. The reasonable physical responses demonstrated that the fractal dimension can be as a quantized value of other parameter in physical space.
