| 摘 要： | 通过X光CT技术对8组不同颗粒尺寸的堆浸散体介质进行了扫描,获得了各自的二维CT图像。利用图像处理方法统计了各散体介质孔隙尺寸分布概率,并进行了拟合分析。结果表明,散体孔隙尺寸呈正态分布,随着样本颗粒粒径的增大,散体平均孔隙尺寸也逐渐增大;散体的平均孔隙直径与渗透系数呈正线性关系,在其它条件保持不变的情况下,随着平均孔隙尺寸的增加,渗透系数逐渐增加。结合CT技术和图像处理方法,能够很好地实现散体介质孔隙尺寸的量化分析。

| Abstract: | Eight groups of ore samples with different particle sizes were scanned with X-ray computed tomography(CT)scanner and their cross-sectional images were obtained.Based on image analysis,the pore size distribution probability of each ore sample was calculated and fitted.The results show that the pore size of granular media appears a normal distribution.With the increasing of particle size of ore sample,the mean pore size increases.The mean pore diameter is positively and linearly correlated with seepage coeffi... |
