摘　　要：建在无限深透水地基上的土石坝坝基垂直防渗体位置和深度对渗流量的影响按现有的计算理论无法确定,本文根据边界元的特点和计算理论,建立适用于解决该问题的计算模型,编制相应的计算程序,并计算分析了防渗墙位置和深度对渗流量的影响,为今后的工程设计提供参考依据。According to the former formula and the experience, the influence to the seepage discharge and the seepage gradient when the cut - off wall＇ s place be changed under the infinite deep pervious foundation were still not be clear. This paper makes use of the Boundary element character and the computational thereoy to abtain the formula model of sovling this problem and to establishes the corresponding computational procedure. The influence of the place and depth of cut - off wall to the seepage was also analyzed. The results can provide the reference for the next engineering design.
