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. |

Soil particles were air-dried first. Two kinds of specimens were used ... The pore-air pressure was applied at the top cap through a polyflon filter that can prevent the water within specimens from seeping out of the upper porous stone.
2.3 Effects of stress state and density on SWCC 2.3.1 Test procedure For wetting tests on compacted specimens by triaxial apparatus, specimens were first isotropically consolidated to a mean total stress pt of 20 kPa and a pore-air ...
4) as follows. py − ua = (σoh − ua)(1 + sinφ′) + (c′+ tanφb(ua − uw)) sinφ′tanφ′ (4) where: ua = pore air pressure, uw = pore water pressure, and φb = friction angle with respect to matricsuction. Relative to Figure 4, in addition to ...
