摘　　要：面板堆石坝坝体沉降因大坝填筑强度、基础地质情况的不同而呈现较大的差异性。通过对某面板堆石坝坝体沉降观测资料的分析,认为在砂卵石基础上大坝高强度填筑虽然会引起坝体较大沉降,但只要大部分沉降量发生在施工期及间歇期,则不会影响蓄水后大坝的运行。The settlement of concrete face rockfill dams varies significantly with different dam filling intensity,and basic geological conditions.With observation data analysis of dam body settlement in one concrete face rockfill dam,the paper holds that intensive filling on sand and gravel will lead to large settlement of dam body,but as long as the majority of settlement happens during the construction and interval period,the operation of the reservoir after storage will not be affected.
