Effects of stress path and prestrain history on the undrained monotonic and cyclic loading behaviour of saturated sand

In this research, several diŠerent kinds of specimen's preparation methods which include the hydraulic transportation method (HY), multiple sieving pluviation method (MSP)and wet-tamped method (WT)were used to compare their initial fabric. Moreover, the anisotropic permeability test was performed to those three kinds of specimens. Then, a series of cyclic simple shear tests was conducted on the specimens of HY and WT to investigate the dynamic deformation properties of the sand. The in‰uence of fabric orientation for each kind of specimens to both permeability and dynamic deformation properties were discussed based on the testing results. It is observed that the diŠerence in fabric orientation of the testing soil given by various sample preparation methods results in the diŠerence of permeability and liquefaction resistance. On the other hand, the strength as well as deformation properties obtained by diŠerent shearing apparatus appear to have diŠerent results. Nevertheless, from the viewpoint of fabric orientation with respect to ‰owing direction and shearing force direction, an identical conclusion can be obtained. These phenomena demonstrate that the anisotropic characteristics of the soil have signiˆcant eŠect on the permeability, shearing strength and deformation behavior.
