摘要

裂隙岩体中的渗流和传统的多孔介质渗流在机理上存在本质的差别，这种差别主要表现为裂隙岩体在各种尺度上存在的非均质性。模拟裂隙岩体渗流的主要困难在于描述这种非均质性。目前的概念模型，包括等效连续体模型、离散裂隙网络模型和混合模型使用了不同的技术来预测裂隙岩体中的渗流。这些模型基于不同的假设和概念框架，有着各自不同的优缺点。在实际应用时，应当根据研究域的具体特点和所要解决的问题的要求对其选择，此外，还讨论了单裂隙的概念模型。

Abstract

There is essential difference between fluid flow in fractured rock and that in conventional porous media; it is presented as the structure heterogeneities over a broad range of scales. The mainly difficulties for simulating fluid flow in fractured rock are the characterization of that heterogeneities. Conceptual models of present day

including equivalent continuum models

discrete fracture network models and hybrid models

use different techniques to predict flow and transport in fractured geological media. Based on different assumptions and conceptual frameworks

these models have respectively different advantages and disadvantages; the selection for application of them should be dependent on the in-situ speciality and the requiring of concerned problems. Besides

the conceptual models for fluid flow in single fracture are also discussed.
