Abstract: In order to evaluate the stability of concrete face rockfill dam under construction and analyze the settlement regularities to optimize the placement of the reverse monitoring instrument, this paper monitored the settlement of concrete face rockfill dam in Fengning Pumped Storage Power Station under construction. The eigenvalues of the monitoring data were statistically and comparatively analyzed. Common settlement regularities were summarized, and suggestions were also made for the optimal layout of settlement monitoring instrument.

Key words: concrete face rockfill dam, construction period, monitoring, settlement, Fengning Pumped Storage Power Station

摘要: 为了评价河北丰宁抽水蓄能电站上水库面板堆石坝施工期稳定性,研究施工期沉降规律,反推监测仪器最优化布置,通过布设水管式沉降仪和沉降测斜管对面板堆石坝施工期沉降进行实时监测,并基于特征值统计法对施工期全时段监测数据特征值进行统计和对比分析。评价了面板堆石坝施工期稳定性,分析面板堆石坝施工期沉降量与填筑速率的关系,总结面板堆石坝施工期沉降的共性规律,并对面板堆石坝沉降监测仪器的优化布置提出建议。
