摘要： 天荒坪抽水蓄能电站下库大坝为钢筋混凝土面板堆石坝，施工期、蓄水初期累计内部沉降量及蓄水竣工后外部变形观测累计沉降量均偏大，且收敛缓慢，目前变形仍在继续。通过对外部沉降观测资料进行处理分析，对其沉降较类似工程偏大的原因从填筑材料、填筑施工和河谷地形等方面进行了分析，对今后的面板堆石坝施工有一定参考借鉴意义。

Abstract: The lower dam of Tianhuangping pumped storage power station is a steel reinforced concrete face rockfill dam. Its cumulative internal settlement during construction and the early period of water storage as well as the cumulative external settlement during operation are larger than the similar dams. After fifteen years, the convergence period is not ended. By means of analysis of the external deformation data, this article presents the reasons in aspects of dam material, construction and valley topography, worthy reference.
Key words: Tianhuangping pumped storage power station, face slab rockfill dam, settlement analysis
