A DDS-70 electric-magnetic dynamic triaxial apparatus controlled by computer is used to determine the modulus and damping of soil in the small rang of strain. After a few affecting factors are studied and analyzed, the value of the modulus and damping of several soils are given as reference and comparison.
Keywords: saturated slity soil; dynamic modulus; damping ratio; dynamic triaxial test
