| Abstract: |
| Take the tailing dam of Yunnan as the research object, simulate the dynamic response under action of earthquake of the dam with GeoStudio software, analysis of seismic dynamic response of the dam on stress, displacement, liquefied area and permanent deformation during the earthquake. The results show that, in the process of earthquake, below of the junction between fill dam and initial dam occurs stress concentration, the maximum horizontal displacement of the dam occurs in the below of fill dam, fill damSwill produceSpermanent deformationSand cracks, Earthquake causesSa largeS??liquefied area ofSsediments. Calculate the stability of tailings with Sweden Arc Method, the minimum safety factor is 1.572, which is greater than the standard value, description the tailings is stable in the case of earthquake. |
