摘要: 采用现有的确定入渗上缘线的方法进行尾矿库三维渗流数值模拟,得到的三维渗流场与实测值有较大的差别。针对这个问题,提出了确定入渗上缘线位置的间接化引方法。以渗流理论和有限元理论为依据,分别选择3种入渗上缘线位置对尾矿库进行三维渗流场的数值模拟,通过与实测结果比较,进一步证明采用间接化引方法确定入渗上缘线的合理性。

Abstract: Using the infiltration upper-edge-line by the existing methods in the numerical simulation of the 3-D seepage field,the larger errors of the numerical results would be caused compared by the testing results.According to this problems,a new indirect conversion method is presented to determine the more accurate location of the infiltration upper-edge-line.Based on the seepage theory and the finite element method,the numerical simulation is carried out to analyze the 3-D seepage field by selecting three different location of the infiltration upper-udge-lines.And the numerical results are compared with the testing results,which shows the validity of the method presented in the paper to accurately determine the infiltration upper-edge-line in the numerical simulation.
