  • This paper analyzes the tailing material of Mijiangou dam and their composion, structural, physical and mechanical characteristics. Tailing material parameters of dynamic characteristics are made certain through vibrational triaxial texts of dynamic characteristics. Index models of dynamic characteristics are studied. It obtains the changing laws of dynamic stress, dynamic modulus, damp ratio, dynamic shear modulus along with dynamic strain, and dynamic stress and destruct vibration, vibration times-pore pressure ratio changing laws. It puts forward a pore pressure model that accords to experimentation results. Then it gets some fruits and conclusions. The results offer a scientific basis and technical guidance for quake-power analysing and aseismatic stability estimation.
