Unsaturated Soils: Research & ApplicationsUnsaturated Soils: Research and Applications contains 247 papers presented at 6th International Conference on Unsaturated Soils (UNSAT2014, Sydney, Australia, 2-4 July 2014). The two volumes provide an overview of recent experimental and theoretical advances in a wide variety of topics related to unsaturated soil mechanics: - Unsaturated Soil Behavior Unsaturated Soils: Research and Applications presents a wealth of information, and is of interest to researchers and practising engineers in soil mechanics and geotechnical engineering. These proceedings are dedicated to Professor Geoffrey E. Blight (1934-2013), who passed in November 2013. |

3 WETTING RATES Consider the two similar loading-wetting paths imposed to a pellet sample having a dry density of 1.3 Mg/m3 represented in Figure 13. In the two tests, once the sample was compacted, a vertical stress of 0.3 MPa was ...
Stress-suction paths (macro and micro) in fast wetting test. Figure 4. Illustration of working principle of the DC method. to achieve a relatively stationary swelling behavior. The final collapse after applying a water pressure reveals ...
The evolution of sM and sm may be also followed in the stress paths plotted in Figure 17. ... Irreversible micro strains begin to develop when the micro suction path hits the “suction decrease” yield function of the pellets.
Vertical and horizontal stresses were measured in a suctioncontrolled K0 oedometer cell. Pellets were compacted at a dry density of 1.3 Mg/m3 ... Stress-suction paths in swelling pressure test. Figure 30. Simulation of swelling pressure ...
Figure 3a shows that the total stress ratios under different matric suction values follow different stress paths than the saturated effective stress path of σ3′ = 0.48 σ1′ for the silty sand.
