DYNAMIC SHEAR MODULUS OF SOIL USING A RANDOM VIBRATION METHOD

The random vibration method is proposed in this study for evaluation of the dynamic shear modulus of soil using the apparatus developed by Hardin, and the results are compared with that obtained by the standard sinusoidal test. The soil specimen made of two kinds of clay and sand were placed in the triaxial cell, and twisted at the top by sinusoidal or random forces through the magnetic coils under uniform confining pressure and drained condition. The shear modulus of soil by sinusoidal vibration was computed from the resonant frequency of the soil specimen-top cap coupling system, and that by random vibration was from the expected frequency which was deduced from the narrow-band process theory. /TRRL/
