摘　　要：浸润线是尾矿坝安全关键控制因素之一,为分析某电厂贮灰坝渗流场状态及浸润线影响因素,采用GEO-Slope软件渗流模块,结合勘察资料和监测数据,选取最不利剖面模拟贮灰坝渗流场及影响坝体浸润线因素。结果表明:1) 在初期坝排渗设施失效,干滩长度50米以下时堆积坝不稳定。2) 贮灰坝浸润线的位置随着干滩长度的减小而上升,随着初期坝渗透系数的减小而上升。研究所得结论能够为电厂贮灰坝的渗流监测及控制提供一定的参考。The infiltration line is one of the key control factors for tailings dam safety. In order to analyze the seepage field status and influencing factors of the seepage line of a power plant’s ash storage dam, the GEO-Slope software seepage module was used. Combined with survey data and monitoring data, the most unfavorable profile was selected to simulate the seepage field of the ash storage dam and the factors affecting the seepage line of the dam body. The results indicate that: 1) In the initial stage, the dam drainage facilities fail, and the accumulation dam is unstable when the dry beach length is below 50 meters. 2) The position of the infiltration line of the ash storage dam increases with the decrease of the dry beach length and the decrease of the initial dam permeability coefficient. The conclusions drawn from the research can provide some references for the seepage monitoring and control of ash storage dams in power plants.
