摘　　要：以单条平直裂隙中的水流运动规律为基础,构建二维裂隙网络非稳定渗流模型。利用算例在多种工况下的计算结果绘制岩体内部渗流水头等值线,并对不同工况下的渗流水头等值线进行合理比较,以获得水库水位变化与坝址岩体渗流场之间的关系以及水位变化后岩体内部水头与边界水头之间的关系。This paper establishs the two-dimensional flow model of unsteady seepage in fractured rock masses based on the rule of water movement in regularity of single crack. According to the example results in different operating conditions, the paper plots and compares the contour graphs of water head in the rock masses, which finds the relationships between the water level fluctuation of the reservoir and the seepage field as well as the relationships between the water head at the boundary and that of interior in the rock mass.
