Variation of Small-Strain Shear Modulus of Unsaturated Silt under Successive Cycles of Drying and Wetting

Khosravi, Ali / Hashemi, Amirhossein / Ghadirianniari, Sahar / Khosravi, Mohammad

A new framework is developed to extend an existing small-strain shear modulus $(G_{\max})$ model to determine $G_{\max}$ of unsaturated silty soils along different paths of the soil water retention curve (SWRC) including the scanning loops. The suitability of the proposed framework is validated against experimental results of a series of bender-element tests performed in this study and data reported in literature. Measured values of $G_{\max}$ showed a slight hysteresis in the $G_{\max}$ measurements along the scanning curves of the SWRC, with lower values along the wetting scanning paths. However, results indicated that the value of $G_{\max}$ was recovered once the main drying path was reached. Results of this study also indicated that $G_{\max}$ behavior of the silty specimen along the scanning curves was stress dependent. The model was observed to follow the experimental data along different paths of the SWRC including scanning curves.
