An apparatus for performing consolidation tests under K0 conditions was designed and constructed for testing unsaturated soils. Three types of consolidation tests are of interest in unsaturated soils. These are: (1) constant water content loading tests, (2) consolidation under a net total stress, and (3) consolidation under a matric suction. The apparatus had been used for simultaneous and separate measurements of pore-air and pore-water pressures for all three types of consolidation tests. The experimental results demonstrate the pore pressure and volume change behavior of an unsaturated soil during these tests.
