Compression characteristics of compacted sand-bentonite mixtures with and without saturation
Compression characteristics of compacted sand-bentonite mixtures with and without saturation
In previous studies, the authors have demonstrated an irreversible change in void ratio with suction change of sand-bentonite mixtures after saturation, while that prior to saturation is reversible. However, it has not been clarified how the compression characteristics differ between sand-bentonite mixtures with and without pre-saturation. Therefore, in this study, one-dimensional compression tests were conducted to investigate this. As a result of the compression tests, both types of materials had nonlinear curvature of the compression line, revealing that the compression index of pre-saturated specimens increase. Furthermore, in this study a reproduction analysis of the test results using the SYS Cam - clay model which can consider the effect of soil skeleton structure was performed and good reproducibility could be obtained.
