In a freeze-thaw cycle test on sand, Harris [13] observed both positive and negative values of PWP. Negative pore pressure resulted from matrix suction under no load, while positive pore pressure was generated under external load. The PWP exhibited periodic changes during freeze-thaw cycles, ...
Therefore, changes in suction behavior of soils in the presence of saline waters are important for engineered barriers. The aim of this study was to determine the change in suction and swelling behavior of soils, which were exposed to salt solutions (NaCl, CaCl2, natural seawater) with respect...
Well drilling is expensive and industry looks forward to approaches to reduce the number of wells required for estimation of the OWC. In this context, this paper presents the proof-of-concept for a probe to measure pore water pressure in oil-water saturated porous rock. This would allow ...
while also observing alterations in the internal cohesion of soil due to root presence. Plant roots can absorb soil water, resulting in negative pore water pressure (i.e., suction) in the soil46,47, which also contributes greatly to the improvement of soil shear strength48,49. Subsequently, ...
Target relative humidity (or total suction) was imposed directly in the ESEM chamber to moisten or dry the soil specimen; the soil microstructure after the moisture equalization which took a long time was observed [15, 16]. (ii) The PSD was measured after consolidation or shear failure to ...

These steps are: (1) at each step, non-wetting fluid invades the widest throat (and adjacent pore) that has the lowest capillary pressure (or suction), (2) regions of isolated wetting fluid, which are isolated clusters of pores and throats filled with wetting fluid, are trapped and ...
