Abstract Earthquake is one of the main causes of tailings dam accident. It is very important to evaluate the seismic behavior of tailings dam in order to prevent earthquake damage of tailings dam. The seismic performance of the tailings dam includes three aspects：liquefaction possibility，dynamic stability and permanent deformation. Based on the finite element time-history analysis method，the dynamic response and seismic behavior of the Dashahe tailings dam in Yunnan Province，which is need to be heightened and expanded，were calculated and analyzed on the conditions of current state，heightening directly and heightening with additional drainage facilities. The results show that the phreatic line has an important influence on the seismic behavior of the tailings dam. When the tailings dam is directly heightened，the phreatic line is obviously uplifted，resulting in that some tailings of the downstream slope are liquefied，a large permanent deformation occurs and the safety factor is reduced to below the standard value. Additional seepage facilities can increase the depth of the phreatic line effectively and improve the seismic behavior of the dam significantly，so as to meet the corresponding seismic fortification requirements. The acceleration amplification factor of tailings dam under earthquake is relatively small and not monotonous with the dam height，which is different with earth-rock dam. The permanent deformation of the tailings dam was calculated by using the sliding displacement analysis method，the equivalent nodal force method and the simplified elastoplastic analysis method respectively. The results of the three methods have obvious differences in their specific values and forms of expression. But a tendency was showed by all three methods that the permanent deformation increased with the dam heightening and decreased with the phreatic line dropping.

Key words： slope engineering tailings dam dynamic response time-history analysis method phreatic line liquefaction permanent deformation
