摘　　要：以西南白鹤滩特高拱坝为研究对象,依据监测数据,从时间序列变化与空间分布两个角度,分析了初期蓄水过程中特高拱坝在径向、切向、垂直向的变形规律。结果表明,拱坝变形与水位具有良好的同步性与相关性,随着水位不断升高,拱坝整体向下游和两岸变形,沉降量减小。在空间分布上,各向变形均以坝中心线为轴大致对称分布,径向变形与垂直变形中间大、两边小,切向变形中间小、两边大。The article focuses on Baihetan particular high arch dam in southwest China.Through the analysis of monitoring data,the initial reservoir filling process of the high arch dam is analyzed from two perspectives:temporal sequence changes and spatial distribution.The results indicate that the deformation of the dam is well synchronized and correlated with the water level.As the water level rises,the overall deformation of the dam shifts downstream and towards both banks,while the settlement decreases.In terms of spatial distribution,the deformations in all directions are roughly symmetric about the centerline of the dam.Radial and vertical deformations are larger in the middle and smaller towards the sides,while tangential deformations are smaller in the middle and larger towards the sides.
