Stress controlled cyclic triaxial tests were performed under different cyclic stress ratios (CSRs) and confining stress of 100 kPa on normally consolidated locally available clay and organic clay with 15% (RO1) and 26% (RO2) organic contents to study the axial strain and pore pressure response. The cyclic stresses were applied at frequency of 1, 0?5, and 0?1 Hz. Isotropically consolidated undrained (CIU) tests were also performed to study the shear strength characteristics of these soils. The results showed that organic clay failed at higher deviator stress than inorganic clay. During cyclic loading, the axial strain in inorganic clay is found to be higher than in organic clay for same CSR and frequency. However, the pore pressure ratio response in organic clay at lower frequency of 0?1 Hz was higher than in clay in the initial cycles of loading. The final pore pressure ratio attained at stabilization was more or less same in both the types of soils.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
