Besides the in-situ soil in Taipei the cement improved soils and other admixed were performed the resonant co;umn tests to study their dynamic properties containing shear modulus and viscous dampimg ratio. The results showed that the shear modulus of in-situ doil and cement improced soil increases with confining pressure, but this viscous damping ratio dexreases with confining pressure, The influence of confining time on dynamic properties is not much. Shear modulus decreases and increases above a threshold shearing strain. Form the result of this study, it is found that the threshold shearing strain increases with admixed od cement.
