ABSTRACT
This paper describes the deformation characteristics of recompressed volcanic cohesive soil obtained from cyclic triaxial tests, and discusses the effects of saturation and drainage on its deformation characteristics. The result is that the equivalent Young’s Modulus of the recompressed volcanic cohesive soil is located within the lower limit of the range of previous studies for marine clays. However, the relationship between damping ratio and axial strain is twice as large as the previous data. The equivalent Young’s Modulus and dumping ratio are dependent on the saturation of the specimen and the drainage conditions.
