Outline of Final Research Achievements

This study is visualized soil structure of porosity distribution and water flow inside of ISO/CEN column test by using the X-ray CT using 3 types soil samples. It is discussed that forming pathway and dissolution mechanisms in column. Water flow in column is made difference of each soil. Toyoura Sand and Decomposed Granite were formed excellence flow path in the vicinity of the tube center. On the hand, Kanto Loam was caused a excellence flow path in the vicinity of the tube wall. The conventional column test is suggested that water flow is different by soil to be used. Thus, it is possible that each column test are caused different the liquid-solid ratio and dispersion in column to filled soil by Physico-chemical characteristics of the soil.
