摘　　要：边坡地下水渗流场分析是边坡稳定性研究的基础,本文以水厂铁矿高陡边坡为研究对象,采用工程勘查,钻孔压水、注水试验等对矿区水文地质环境进行了调研,并采用有限单元法对I地质分区边坡剖面进行了渗流场模拟研究,预测了边坡开挖至最终境界时的水压分布状况,为边坡稳定性研究提供了可靠的渗透系数和渗流场分布情况。The analysis of groundwater seepage is the base of calculating and studying the slope stability. Taken a high and steep slope of Shuichang iron openpit as a research object, the hydro-geological environment in mining area is investigated based on engineering means such as prospecting,forced water and borehole water injection tests. In addition, the finite element method is used to simulate seepage field of a typical slope profile and the seepage distribution of the slope at final limit of this openpit is forecasted. These provide reliable and essential parameters for the optimization of slope stability.
