Abstract
In all branches of the soil mechanics, it is important that we know capillary mechanism of soil. But it is a very difficult question to discuss, since capillary systems of soil have many complex elements. In this paper the author discuss quantitative and structural properties of soil capillary based on electro-phenomena and permeability. The results indicated the following:
(1) The quantities of capillary system in single structural soil such as sand have close relations to the gradation, particle size and degree of compaction.
(2) The used method is a convenient and easy procedure to observe the capillary organism and density of soils.
In these studies, it is assumed that capillary condition of soil consists of idealized systems.
