在边坡稳定问题中,地下水对边坡稳定的影响起着重要的作用,往往成为导致滑坡的直接原因。地下水除了软化岩体降低其强度外,还以渗透压力作用于坡体,使稳定条件趋于恶化。文章论述了流场的数值分析,对露天矿在开采过程中求解各时刻或各开采水平条件下的流场特征,并能描绘出场内渗流压力分布的直观图象,为边坡稳定性分析 In slope stability problems, groundwater plays an important role in the stability of the slope and often becomes the direct cause of the landslide. In addition to softening rock mass, groundwater reduces its strength, but also osmotic pressure on the slope, the stability conditions tend to deteriorate. In this paper, the numerical analysis of flow field is discussed. The characteristics of the flow field at different times or mining levels in the open pit mine are plotted, and the visual images of the on-site seepage pressure distribution can be plotted to analyze the stability of the slope
