  2. Saturated sand are testes in the laboratory under the undrained cyclic loading condition with static - dynamic dual purpose triaxial compression test apparatus, which is designed under the cooperation of hohai university and marui co. ltd japan. the results indicate that the stress path approaches from a initial stress point to the failure lines as cyclic loading goes on, and eventually converges on a certain limiting stress path in the vicinity of the failure lines. the stress - strain curve, however, does not converge on a closed hystersis loop ; the shear strain rapidly increases in looser sand or gradually and continually increases in denser sand
