| 内容記述 | This paper is the observation on the factors which exert an influence on forming of frost heaving. These factors are soil moisture, temperature of refrigeration and soil condition. And then, the object of this investigation is to find the rational method of the control of frost erosion. The results are summarized as follows: 1) Soil moisture…… Ice filament was formed on the presence of water in the soil within pF 3.0, it was made from pure water at the moisture content of pF 0～2.0, but on the presence of water of pF 2.0～3.0 soil particles took partiary in it, the volume of ice filament was approximately in proportion to the volume of water in the soil. 2) Temperature of refrigeration…… The volume of ice filament increased with the effective accumulative temperature, and the curve of this relation was fitted a straight line. 3) Nature of soil…… It is recognized that the form of ice filament was alike to the locus of the pore space in the surface soil, and that the volume and the form of ice filament depended on the soil conditions. 4) Direction of slope…… Frost heaving was most repeatedly found out on the north slope, and its frequencies decreased in order of the east, the west and the south slope. 5) Method of control…… The most effective method was to cover the ground surface with the object of intercepting the thermic conduction. | |||||||
