Abstract: The Toushishan tailing bond is a proposed new tailing bond, and according to specification requirements, its level identified as second class tailing pond. The tailing pond is in 8 degrees in quake zone, and its dynamic stability should be paying attention. The Toushishan tailings in a seismic dynamic liquefaction under the action of the calculation and analysis was calculated and analyzed. It can provide the reference for tailings dam in high intensity earthquake region design and management.

Key words: Tailing dam, Earthquake, Dynamic liquefaction
