摘　　要：结合抚顺西露天矿的地质环境背景,介绍了抚顺西露天矿南帮滑坡变形监测中地下水监测系统的构建情况。从降水入渗、岩体的透水性等角度对比了汛期及非汛期地下水的监测数据,并利用SPSS统计分析软件对单点地下水位变化值和滑坡位移变化值进行曲线估计回归分析并建立模型。结果表明,汛期持续强降雨是诱发西露天矿南帮滑坡变形的重要因素;强降雨入渗过程中,基岩裂隙水的变化存在明显的滞后性;单点地下水位变化值和滑坡位移变化值符合三次项曲线模型;非汛期,地下水位逐渐降低,滑坡地表变形速率也减缓。Combined the geological background,the construction of groundwater monitoring system in the landslide deformation control of the south part of the open pit of the Western Opencast Coal Mine in Fushun,Liaoning Province is introduced. The monitoring data of groundwater during flood season and non-flood season were compared with the view of precipitation infiltration and the permeability of rock mass. The SPSS statistical analysis software was used to analyze the regression of water level change value and the landslide displacement change value in single point and the model was established. The results show that the continuous heavy rainfall in flood season is an important factor to induce the deformation of the south slope of the south open pit. During the heavy rainfall infiltration process,the change of the bedrock fissure water is obviously lagging behind; the water level change value and the landslide displacement change value in single point coincides Cubic curve model; in non-flood season,the groundwater level is gradually reduced,the landslide deformation rate also slowed down.
