该文首先讨论了边界无法处理渗流问题的计算原理，针对露天矿山边坡裂隙岩体的渗透特性，建立二维渗流模型，采用边界元数值方法模拟分析各向异性岩体地下水在排水孔疏于过程中的渗流场分布特征，并应用于露天矿现场实例之中。
In this paper, the calculation principle that the boundary can not handle the seepage problem is discussed first. According to the seepage characteristics of the open-pit mine slope rock mass, a two-dimensional seepage model is established, and the boundary element numerical method is used to simulate the analysis of anisotropic rock- The process of seepage field distribution characteristics, and applied to the case of opencast mine site.
