三维裂隙网络的多边形单元渗流模型

A fluid-flow model for three--dimensional network of Polygonal fractures

文中以裂隙互相切割后的多边形为基本单元,提出了一个裂隙网络模型生成及渗流计算方法。通过在一个假想模型上的渗流计算发现,裂隙网络模型与多孔介质模型在水位计算上有很大的差别。

A method presented in this paper is to establish three dimensional fractured network models and to calculate the fluid-flow of the models. This method is based on polygonal fractures intersected each other. Through the calculating analysis of theoretic models, it is discovered that there is much difference of the calculating water head distribution between the fractured network model and the equivalent porous medium model.
