Outline of Final Research Achievements |
If it is possible to quantitatively interpret the current level of oxidation-reduction state of clayey soil reached anaerobic restoring ability and to what level it reaches based on the limit, it can contribute to the elimination of contradictions between physico-chemical and engineering properties in clayey soil in the formation. The following representative results on the research were obtained: 1) There was no significant change in oxidation-reduction potential, pH and electric conductivity of clayey soil which gave periodic redox cycle of 574 days; 2) Permeability of the clayey soil increased; 3) In the analytical study on the change of the ground environment, the method which of manipulating the permeability to a high level in order to conform to the actual phenomenon does not contradict the scientific point of view.
