In order to investigate the character of compacted cohesive soil, a series of cyclic compression tests was performed. And the volume changes of specimens also measured.
The following results are obtained.
1) The cyclic compression tests are very useful to denote the failure process of cohesive soils. 2) The volume change character is closely conected with the following factors which indicate the change of soil structure.
Factors; Ene, Enl, Enp, εe, εp, εe/εt, dδ/dε.
3) The pseudo-elastic area on εe-εp curve, the uncontinuous point on (εe/εt)-εp curve and thebranching point of Ene-εp curve and Enl-ep curve show the sudden change of structure of soil.
