裂隙是孔隙的一类。文章利用土壤切片的数字图像,采用目视分离的方法,比较研究了裂隙与其它类型的孔隙在结构上的差异、选择的土样研究结果表明,目视分离裂隙的方法是可行的,土体中的裂隙直径分布曲线是不规则的,而其它类型的孔隙直径分布曲线则类似对数正态分布;土壤总孔隙中直径较大的部分主要由裂隙构成,直径较小的部分则由其它类型孔隙和裂隙共同构成;土壤表面裂隙与土体内部裂隙在结构上可能具有一定差异。
Crack is a kind of pore. The article uses the digital image of the soil slice, uses the method of visual separation, compares the structural difference of fissures and other types of pores comparatively. The results of the selected soil samples show that the method of visual fissure separation is feasible, In the distribution of pore diameter is irregular, and other types of pore diameter distribution curve is similar to logarithmic normal distribution; soil total pore diameter of the larger part of the main fractures, the smaller diameter part of the other types Pores and cracks together constitute; soil surface cracks and cracks in the soil may have some differences in structure.
