摘　　要：本文基于原型监测,通过沉降、水平位移两个方面分析某抽水蓄能电站施工期上库主坝内部变形情况。分析结果表明,主坝自2014年10月以后沉降速率均已达到设计控制指标,沉降量和水平位移量均不大。与一般面板堆石坝相比,沉降和水平位移变形规律略有差异,由于受坝基地形倾向下游的影响,上水库主坝施工期最大沉降位置靠近下游,水平位移也整体向下游变形。This article is based on prototype monitoring to analyze internal deformation of a pumped storage power station during the construction period in two aspects, horizontal displacement and vertical displacement. The results of analysis show that the settlement rate of the dam has reached the design demandsin October 2014, and the deformation values are small.Compared with the general concrete face rockfill dam, the horizontal and vertical displacement is slightly different.Because of the influence of the terrain, the maximum settlement position of the dam is close to the downstream, and the horizontal displacementis also deformed downstream.
