Outline of Final Research Achievements |
This study aims at making aggressive contribution of geotechnical engineering to the global environmental problems, through the technical proposal of desertification deterrence against salt damage. As to desertification, over-logging, overgrazing and salinization are the three major factors, accounting for the approximately 80% of entire desertification. It is caused by the deviation of the water circulation between the aerospace and the ground due to deforestation, especially the desertification due to salinization is caused by high concentration of salinity, basically diluted in the underground water. Such salt damage is observed in a wide range of areas of the Eurasian continent. In this study, a FE simulator which can represent the desertification mechanism by such salt damage is developed and a salt damage deterrence construction method is developed with taking account of utilization of granular materials such as recycling of PS ash and water purification plant sludge.
