| 摘 要： | 非饱和带裂隙岩体中的渗流和饱和带相比有其不同的特点，包括毛细管流、薄膜流、优先流和裂隙-基质相互作用等。这些特点导致非饱和带裂隙岩体中的渗流具有相当的非均质性。笔者描述了裂隙岩体中非饱和渗流的这些特点，并简单讨论了目前所存在的模拟非饱和渗流的概念模型。

| Abstract: | There are some special issues that cause difference to predict fluid flow in fractured vadose zone, including capillary flow, film flow, preferential flow and fracture-matrix interaction. Those issues can bring on notable unevenness of local velocity and flux in fractured vadose zone. The features of those issues are studied. In addition, alternative conceptual models for flow in fractured vadose zone, such as macroscale continuum models, high-resolution finite differences models, discrete fracture networks models, percolation models and weeps models, are discussed. |
