説明

The purpose of this study is to clarify the recovery from the residual strength of landslide soils and the influence of the effective normal stress on strength recovery.<BR>The recovery of the shear strength of the samples contained high amount of sand particles subjected to large-displacement shear by re-consolidation was clearly detected at the effective normal stresses below 150 kPa. The recovery rate increased with the decreasing normal stress but the strength did not recover to the level of the fully-softened strength. Furthermore, for the samples contained high amount of clay particles, the rate of decrease in the strength against the peak strength was great but the recovery rate was negligible at the whole normal stress. The differences between the recovered strength and the residual strength were 1°-3° for the samples contained high amount of sand.
