Abstract

Abstract: Based on the geological prospecting data of Manyuan Iron Ore Tailings, this paper generalizes the dam axis section in a reasonable manner, applies numerical simulation methods to analyze the seepage field of the tailings dam on the condition of flood.According to the seepage data, it studies the dynamic response of the tailings dam cofunctioned by flood and horizontal earthquake.Through calculation and analysis the results show that the tailings dam can operate well under the unfavorable condition.

Key words: tailings dam; seepage field; the earthquake response; dynamic stability
