Shear Strength Behaviour of Unsaturated Silty Soil
Summary This paper presents results of an experimental study on shear strength behaviour of an unsaturated silty soil. A comprehensive set of laboratory experiments have been undertaken in a double-walled triaxial cell (and a conventional cell for saturated samples) on samples of a compacted silty soil. In the experiments the soil samples were subjected to isotropic consolidation followed by unloading and subsequent anisotropic reloading (shearing) under constant suctions. Volume change and shear strength data for the samples were monitored continuously during the experiments. In this paper, the results of the experimental study will be presented and the effects of suction on the shear strength and volume change of unsaturated soil will be discussed in detail.
