摘　　要：为研究面板堆石坝的沉降变形量值范围及变化规律,通过国内已投运的典型面板堆石坝实测沉降变形监测数据,统计、分析了不同坝高的大坝在施工期、运行期的沉降变形量值范围、分布规律及影响因素,结果表明:百米级面板堆石坝最大沉降量一般在坝高的1%以下,且其大小与坝高、填筑体抗压强度、施工工艺、施工质量等密切相关。研究成果能够为新建和已建工程运行期沉降变形安全监测提供有益指导。In order to research the deformation laws of concrete face rockfill dam(CFRD),the measured settlement deformation monitoring data of typical concrete face rockfill dams in operation in China are studied.The settlement deformation variation range,distribution laws and influencing factors of the dams with different dam heights during construction and operation are counted and analyzed.The results show that:the maximum settlement of concrete face rockfill dam at 100 m level is generally less than 1%of the dam height,and it is closely related to the dam height,compressive strength of the filling body,construction technology and construction quality.The research results can provide useful guidance for safety monitoring of settlement deformation of newly-built projects and existing projects during operation.
