On the contrary, in the unsaturated systems volume change measurements are complicated by the compressibility of air. If an increase of confining pressure is applied to an unsaturated sample, a movement of water out of the sample will occur but at the same ...
The saturated GDS Back Pressured Shearbox (GDSBPS) is used for direct shear testing on soil specimens with control of sample pore pressures. Two versions of the GDS back pressured shearbox exist (Saturated and Unsaturated). Both versions allow the pore pressures ...
GDS Unsaturated Triaxial Testing of Soil (UNSAT) is an extension to traditional triaxial testing in that soils from above the water table may be tested under conditions approaching the in-situ stress state and degree of saturation or partial saturation. All ...
