Abstract
Static liquefaction is one of the main causes of flow slide destruction in tailings pond. This paper analyzed the static liquefaction behaviors in tailings pond through the development of displacement, deformation and pore pressure ratio. Based on the simulation results, some conclusions were obtained. Fast discharge of tailings will fasten the increase of pore pressure. The dam-toe in tailings pond is very easy to be eroded, leading to introverted destruction. The liquefaction of sand layer in foundation would cause the tailings dam’s slip failure. With the arising of tailings, pore pressure increased continuously expanding to the foundation under the dam.
