Suction controlled oedometric tests: analysis of some experimental aspects

Risultato della ricerca: Otherpeer review

Abstract

The results of suction controlled oedometric test on compacted clay samples are discussed with reference to some aspects of the axis translation technique. The air overpressure procedure, based on a very gradual increment of the pore air reference pressure, is proved suitable in tests on samples with high saturation degree even when high intensity air pressure increments are requested. The effects of the axis translation on the recorded soil water volume changes, due to air diffusion through the HAEV ceramic disk and soil water evaporation to air pressure line. Are analyzed using of suction controlled wetting and drying tests
