基于渗透张量的裂隙渗流有限元计算中反常水头现象初探

针对利用等效连续导水介质模型研究岩体裂隙渗流问题时，有限元计算部分结果出现的水头反常现象，经多因素分析，认为渗透张量与渗流区域边界形状之间存在着相互协调的条件，当这种条件被超越时，就会使计算结果出现水头反常现象。

Primary Research on Abnormal Waterhead Phenomenon in Fracture Seepage Finite Element Method Based on Permeability Tensor

During researching the problem of fracture seepage in rock mass with the equivalent continues media model, the abnormal water head phenomenon of some nodes were found by the finite element method. After analyzing many kinds of influence factors, the main influence factor can be defined as follows: if the mutual coordinate condition between the permeability tensor and the shape ofseepage region boundary is broken, the abonrmal waterhead phenomenon of some nodes will occur bythe finite element method.Zhao Jian Assoc.
