| Outline of Final Research Achievements |
Liquefaction due to earthquake induces the upward movement of water in the ground. As a result, a looser part is formed underneath the non-liquefiable surface layer. This part becomes weak part in the ground and causes the severe damages for infrastructures. In this research, liquefaction resistance not at the looser part due to inflow, but at the denser part due to outflow of pore water were studied by the laboratory element tests. The decreasing and increasing ratio against undrained liquefaction resistance were suggested and evaluated quantitatively.
