Abstract: By studying the monitoring method, value range, influencing factors and variation law of slab deflection of typical concrete face slab rockfill dams taller than 100 m that have been put into operation in China, the reasonable value range and possible influencing factors of slab deflection are obtained. Combined with the experience of on-site inspection of the face slab, the conclusion is obtained that there is a slim chance of bending failure when face slab is only partially damaged. Therefore, to control slab deflection, control of the dam body deformation is only needed.

Key words: face slab rockfill dam, face slab deflection, measured behavior

摘要: 通过研究国内已投运的、坝高100 m以上的典型面板堆石坝实测面板挠度监测方法、量值范围、影响因素及变化规律,得出面板挠度的合理量值范围及可能的影响因素。结合面板运行多年来的现场检查情况,得出面板仅局部破损时发生弯曲破坏的可能性不大,由此反映出控制面板挠度仅需控制坝体变形,供参考。
