Abstract: First impounding would exert great influence on safety and stability of earth-rockfill dam, so seepage monitoring is important. According to regression analysis on seepage monitoring data of Yunpeng dam, this article analysed variation of water level and seepage. Further, the seepage operation state was appraised, to provide reference for dam operation management and completion acceptance.

摘要： 土石坝首次蓄水对大坝安全稳定影响较大，加强和重视初蓄期大坝渗流监测尤为重要。通过对云鹏大坝初蓄期渗流监测数据的回归分析，掌握坝体水位及渗流量变化规律，判断大坝渗流运行状态，为大坝竣工验收及运行管理提供参考。
