Abstract
An experimental investigation was conducted to study the effect of pore fluid chemistry on the dynamic behavior of reconstituted marine clay. Sodium chloride solution of 0.4 M and 1 M concentrations was used to induce the physicochemical changes. Strain-controlled undrained cyclic triaxial tests were carried out to evaluate the most important parameters such as shear modulus and damping ratio at a large strain range. The results showed that the effect of pore fluid was more pronounced on cyclic shear modulus values at a strain amplitude of 0.3–1%. Tests were also conducted to study the effect of physicochemical factors on the degradation of normalized modulus GN/G1 of marine clay specimens reconstituted with distilled water and salt solutions.
