Abstract
Different specimen preparation methods such as moist tamping, dry funnel deposition, slurry deposition, dry air pluviation have been reported in the literature to investigate the undrained behavior of silty sands. Similarly, different means have been used to densify the soils prepared with such methods. Ongoing research shows that the change in undrained behavior (e.g. change in initial peak deviator stress and instability angle) due to different deposition densities is significantly affected by the densification technique utilized within a particular deposition method. It is believed that those variations are closely related with changes in the initial soil fabric that is achieved after the deposition. In this study, a relatively new densification technique, avoiding mold tapping, is used with the dry funnel deposition method. This new method of densification is thought to create a soil fabric that is much closer to the initial fabric than other techniques. The experimental results show that the change in undrained behavior with increasing density by densification is much less pronounced when compared to the other densification methods reported in the literature.
