...Xi Xiong; Shun-ichi Kobayashi; Hiroyuki Izumi; Feng Zhang Microporous membrane (MM) filters with a significantly thin thickness have recently been used as an alternative to ceramic disks for matric suction control in the axis-translation technique for element tests on unsaturated soils. Although...

... can be determined. The apparatus utilizes the hanging column and axis-translation techniques to control suctions in 0∼5 kPa and 5∼600 kPa. It is suitable for investigating water/oil retention, isotropic compression, and triaxial shear behavior of oil-contaminated soil. Using this new apparatus, five...

...Snehasis Tripathy; Hesham Elgabu; Hywel R Thomas Matric suctions of several compacted soil specimens of a low-plastic soil were measured using null-type axis-translation technique. The study showed that in general, the dynamically compacted specimens reached equilibrium sooner than the statically...

..., saturation is achieved by back-pressure while matric suction during unsaturated tests is imposed to the specimen assuming valid the axis-translation technique. The paper describes details of the new device, the testing methodology, as well as presents a series of drained conventional triaxial compression...

...Kenton C. Power; Sai K. Vanapalli The null pressure plate apparatus is conventionally used in the measurement of matric suction of fine-grained unsaturated soil specimens applying the axis-translation technique. This apparatus is typically used to measure the matric suction in the range of 50–500...

... validation of its suitability for testing unsaturated soils. The device features two independent pore-air pressure and pore-water pressure control/monitoring systems. Matric suction states in the specimens are induced and maintained constant during testing by using the axis-translation technique. A companion...

... and suction-controlled conditions. The experiments were conducted in a stress/suction-controlled true triaxial (cubical) setup following a multi-stage testing scheme. Matric suction states in the specimens were induced and maintained constant during testing by using the axis-translation technique. Imposed...
