coarse tailing sands and fine tailing sands all were prepared by artificial partitioning experimentation in accordance with the requirements of central line damming. DDS70 electromagnet kinetic equipment was used to study the dynamic strength
stressstrain 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.
