Abstract: In this paper, the monitoring data of a concrete face rockfill dam (CFRD) in a deep and narrow valley during construction and early impoundment are analyzed, and the monitoring results of some typical sections are compared with those calculated in design stage. Through these analyses, we can know systematically the working status of main parts of the project, such as dam body, concrete face and peripheral joints. These results can provide technical references for subsequent impoundment, daily operation management, deformation and seepage prediction, feedback design of similar projects.

Key words: 200 m grade high CFRD, early impoundment period, operation state

摘要： 对深窄河谷上某水电站面板堆石坝在施工期和蓄水初期的监测数据进行整理分析，以及对典型断面监测成果与设计计算成果进行比较分析，较系统地了解了坝体、面板、周边缝等主要部位的工作性态，为后续蓄水、日常运行管理、变形渗流规律预测、反馈设计以及类似工程建设提供技术参考。
