采用FLAC软件对湖南某尾矿坝的稳定性进行了数值模拟分析,绘制出该尾矿坝的位移分布云图,应力分布云图及剪应变分布云图,这些模拟分析结果可为综合分析该尾矿坝的稳定性提供参考,对于确保该尾矿库长期安全运行具有重要的现实意义.分析结果还显示该尾矿坝的安全系数为1.25,在正常状况下尚能安全运行,但考虑该尾矿库所处地区气候湿润多雨仍存在安全隐患,为此文章根据分析结果提出了安全保障建议.

The numerical model of a certain tailings dam in Hunan was simulated and its stability was analyzed by FLAC,and the displacement contours,stress contours and shear strain contours of the tailings dam were drawn. These simulation results have a long-term important practical significance and provide a reference for the comprehensive stability a-nalysis of the tailings dam. The analysis result shows that the safety factor of the tailings dam is about 1. 25 and it is safe in normal condition. However,the dam break may happen when storm comes in this area. So,according to the analysis result,the suggestion of safety measures for the tailings dam is given.
