摘　　要：复杂多变不均匀介质中各向异性地下水渗流是非线性的,采用三维有限元数值分析是处理实际多介质复杂边界条件的渗流问题的有效方法。导出了三维渗流数值模型,实现了三维渗透流动问题任意渗出面的迭代求解。通过对高陡边坡三维渗流问题的实例计算,得到了计算水平各个剖面的浸润线图,结果表明与实际情况相符,为边坡安全设计、工程处理提供依据。图6,参11。Anisotropy groundwater seepage of complex & asymmetric medium is non-linear, and adopting three-dimension finite element analysis is an effective method to solve the seepage problem for complex border of multi-mediums. Setting up the numerical value model of three-dimensions seeping to realize it eration solution of random seeping surface, getting the each infiltration line chart of accounting level sections through example calculation of high steep slope three-dimension seeping by surface water system. The result shows that it matches actuality well. It provides guidelines for safety plan of slope and engineering disposal. 6figs. ,11refs.
