Abstract

In recent years, desaturation of loose sand deposits as a countermeasure against liquefaction attracts great attention of engineers. Methods of desaturation such as the air injection technique were developed and the relationship between degree of saturation and liquefaction resistance has already been established. In this study, an attempt was made to identify the area at a site by using the threedimensional resistivity tomography, where in-situ air injection test were conducted. It is confirmed that the area where resistivity of soil changed by air injection coincides with desaturated area. Distribution of degree of saturation in the area can be also estimated using the Archie's formulas and the resistivity change.
