摘　　要：尾矿库水位是影响坝体稳定性重要因素之一。为了得到不同水位下坝体安全运行状况,首先采用Geo Studio软件中的SEEP/W模块,对不同水位下坝体渗流场进行分析,然后将SEEP/W的分析结果导入SIGMA/W模块,对坝体的应力场进行分析,最后运用SLOPE/W模块,分析得到不同水位下潜在滑移面位置和边坡安全系数。运用Geo Studio软件对坝体进行流固耦合分析,可掌握不同水位下尾矿坝运行状况,得到的结果也更加符合实际情况。The water level of tailings dam is one of important factors which affect dam stability.To know the running situation of dam at different water levels,firstly SEEP/W module of Geo Studio is used to analyze dam seepage field.Secondly,analysis results of SEEP/W are input into SIGMA/W in order to analyze stress field of the dam.Lastly the SLOPE/W module is applied to obtain the position of latent slide interface and slope safety factor under varied water levels.By coupling analysis of the dam based on Geo Studio,the running situation of tailings dam under different water levels is understood and the results are more reliable.
