摘　　要：目前,对岩体水流系统数学模型的研究主要集中在裂隙渗流模型上,可归纳为四种类型的渗流模型,这些渗流模型仍采用连续介质理论的成果,对于真实岩体非连续介质渗流模拟有较大的误差,同时,由于岩体工程及模型结构和参数的非确定性,这些渗流模型预测的可靠性受到质疑。提出岩体非连续介质渗流概念模型,即"孔隙-裂隙-岩块"三重介质渗流耦合模型,以期提高渗流模拟的拟真性。At present, the study on mathematical model of seepage system of rock mass focuses on the model of seepage in fractures. It includes four kinds of seepage models, which all adopt the theory of continuum seepage. Therefore the simulation of non-continuum seepage in natural rock mass is not accurate. Also, because it is hard to determine the parameters of rock mass model, the reliability of these seepage models is doubted. The triple-media (holes, fractures and blocks) coupling seepage model is presented in this paper, which can improve the reliability of seepage simulation.
