SHEAR STRENGTH PROPERTIES OF A COMPACTED UNSATURATED SILTY SOIL
This paper describes a laboratory investigation of shear strength properties of unsaturated silty soil with known overconsolidation ratio (OCR). A comprehensive set of laboratory experiments has been carried out in a double-walled triaxial cell (and a conventional cell for saturated samples) on samples of compacted silty soil. In the experiments the soil samples were subjected to isotropic consolidation followed by unloading and subsequent anisotropic reloading under constant suction and known overconsolidation ratio.The results show that shear strength is dependent on suction and also both shear strength and axial strain change with variation of OCR at constant cell pressure.
