| 摘 要： | Tailing sands, coarse tailing sands and fine tailing sands all were prepared by artificial partitioning experimentation in accordance with the requirements of central line damming. DDS 70 electromagnet kinetic equipment was used to study the dynamic strength, stress strain relationship, dynamic modulus and damping ratio of three tailing sand types. The dynamic strength and parameters were determined, and some influential factors, such as particle composition, confining pressure, consolidated stress ratio and dynamic stress, were discussed. The test results provide basic data for the stability evaluation of the Yangla copper tailing dam under a magnitude 8 earthquake.
