Outline of Final Research Achievements |
To determine Soil Freezing Curves (SFC) with some soils under the difference speed of soil temperature change and the water, the soil freezing experiments were carried out using Toyoura sand and decomposed granite. The results from these experiments are as follows: (1)Soil Freezing Curves of Toyoura sand using tap water and distilled water are very differ despite under the same soil water content and speed of soil temperature change.(2)Soil Freezing Curves of Toyoura sand under same soil water content are similar despite under the difference speed of soil temperature change. (3)Soil Freezing Curves of Toyoura sand and decomposed granite under same soil water content and speed of soil temperature change is similar except for immediately after the super cooling.
