本文简述了裂隙岩体渗流两类基本模型──等效连续介质模型和离散介质模型的基本理论及其有限元模拟，讨论了两类模型的优缺点，并研究了等效连续介质模型的适用性．本文基于水头连续、结点流量平衡的原则，提出了结合上述两种基本模型优点的耦合模型，给出了相应的有限元计算格式．计算实例表明，该模型是合理、可行的，具有很强的实用价值。
In this paper, two basic models of seepage of fractured rock mass are briefly described: the basic theory and finite element simulation of equivalent continuum model and discrete medium model, the advantages and disadvantages of the two models are discussed, and the effects of equivalent continuum model applicability. Based on the principle of continuous flow head and balanced flow of nodes, this paper presents a coupled model combining the advantages of the above two basic models, and gives the corresponding finite element calculation format. The calculation example shows that the model is reasonable and feasible and has strong practical value.
