Abstract
Cyclic undrained and drained triaxial compression tests were run to define the cyclic undrained strength and to obtain the cyclic strength parameters of a plastic marine clay. In particular, importance of the effect of drainage on cyclic strength was emphasized. The undrained strength calculated by using the methods formerly proposed by authors was proved to fit well with the one observed in monotonic loading triaxial compression tests after cyclic loading. According to the effective stress analysis, a similarity of clay behavior after undrained and drained cyclic loading to behavior of over-consolidated clay without any cyclic loading history was pointed out on the stress path and the stress-strain relationship, respectively. For the covering abstract of the conference see IRRD 287689. (Author/TRRL)
