In order to estimate the deformation behavior of natural sediments, the method with resistivity measurement was examined. From resistivity measurement, it is possible to obtain non-destructive data of sediments. The experimental results showed that the resistivity of natural sediments changes with the structural change due to loading. Furthermore, it was found that the failure of natural sediments could be predicted from the resistivity. Therefore, it is possible to predict the change in mechanical properties and the behavior of soils from the resistivity measurement.
