摘要
以温庄尾矿库尾矿坝为研究对象,采用GeoStudio数值模拟软件,考虑了尾矿坝饱和与非饱和情况下,对现状坝高(+2 310 m)在两种工况下(正常、洪水)的渗流场进行二维数值计算,得到了不同工况下尾矿坝的浸润线埋深、地下水的流速矢量云图、总水头云图和孔隙水压力分布云图等。根据计算结果,对温庄尾矿库尾矿坝的渗流稳定性作出评价,并提出了改善坝体渗流的措施,研究成果可为该尾矿库的安全运行提供参考。
In this paper,the tailings dam of Wenzhuang tailings pond is taken as the research object.Considering two working conditions(normal,flood),the seepage field of the tailings dam at the current level(+2310 m)was simulated by GeoStudio using two-dimensional numerical simulations.The depth of the seepage line of the tailings dam,the velocity vector cloud diagram of the groundwater,the total head cloud diagram,and the pore water pressure distribution cloud diagram under different conditions were obtained.Based on the calculation results,the seepage stability of tailings dam of Wenzhuang tailings pond was evaluated and measures to improve the stability of seepage were proposed.The research results can provide reference for the safe operation of the tailings.
