紫金山露天金矿边坡地下水渗流场分析

渗流计算的目的在于求得各渗流要素，以在边坡稳定性分析、选择合理排渗或加固方案设计中起到提供基础资料的作用。采用数值计算方法更能符合和满足工程条件和需要。通过分析得到了以下结论：因地下水埋深较深，加之天然地下水流向与坡面反向，边坡靠帮后，在坡面的疏干作用下，边坡为有利于稳定的干边坡；终了计算得出的地下水位线，是根据目前资料而定的，实际地下水位线只能通过有限的工作，建立研究区内的裂隙水水文地质模型得到。

Analysis of Underground Water Seepage Field in Slope of Zijingshan Open Pit Gold Mine

The Seepage analysis of slope is aimed at calculating seepage factor so as to provide essential data for the stability analysis of slope and selecting reasonable design scheme of consolidation or seepage drainage. For results calculated by numerical method can meet the conditions and requirements of practical engineering, this paper adopts numerical method to calculate the underground water seepage in slope of Zijingshan Open Pit Gold Mine. The conclusions drawn from the analyses follow as: because the level of underground water is more low, the flow direction of natural underground water is opposite to the slope face, after final slope being achieved, as a result of draining action of slope face, the slope is stable dry slope; the calculated level of underground water is based on present statistics, the actual level of underground water can be obtained only if the hydrogeologicalc model concerning fissure water is established though finite work.
