摘　　要：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。The paper firstly discusses the computing principle of the boundary element method to treat the seepage problem. Aiming at the seepage characteristics of the fissured rock mass of open pit mine slope, it establishes the two dimensional seepage model. Adopting the boundary element numerical method, it simulates and analyzes the seepage distribution features of groundwater in the anisotropic rock mass in the dewatering process of the drainage hole, and applies to a practical example of open pit mine site.
