溶液浸泡对华南地区红砂岩孔隙度和分形维数的影响
Influence of solution soak on porosity and fractal dimensions of red sandstone in southern China
摘要
Abstract
In order to investigate influence of solution soak on porosity and fractal dimensions of red sandstone.A method of image segmentation with grads information added is applied to segment SEM images of the red sandstone,then the binarization of segmented images is implemented.The porosity of the red sandstone is derived and the structure of micro pores is studied.The results show that microscopic pore structure of the red sandstone is fractal.The calculated porosity are agreed well with the experimental data.The porosity and fractal dimensions of red sandstone increase slightly as soak time growing up,and finally tend to be stable when the soaking time approaches 30 days.The influence degree of different salt solutions on porosity and fractal dimensions of the red sandstone is as follows:magnesium chloride ＞ sodium chloride ＞ sodium chloride.关键词
