In order to inverstigate the properties of cohesive soil, a series of creep tests and triaxial compression tests of the material were repeatedly performed. The distinctive feature in these tests was in measuring the changes in the volume of the specimens under undrained condition, since the specimens were partially saturated. The following results were obtained. (1) There are several properties in respect of volumetric changes of the clay specimens that are clearly recognized as characteristics in common both of the triaxial compression tests and the creep tests, evidently so in particular during the unloading process of both these tests. (2) One characteristic of the volumetric change of the specimens is what will be called "the expansion point" which is apparent during the increasing process of the axial load, and which is considered to be the critical point in the transition of energy from the elastic state to the plastic state of the clay.
