摘　　要：吉林台一级水电站混凝土面板堆石坝的坝体和面板在施工期及蓄水期的变形监测数据显示:坝体最大沉降量为77.1 cm,最大沉降率为0.948%。经分析得知,沉降主要大受坝填筑材料和水库蓄水的影响,且混凝土面板的垂直接缝、周边缝、钢筋应力、挠曲变形随水位抬升呈规律性变化,并与坝体内部变形监测数据相吻合。该监测数据为分析整体大坝变形形态提供了依据。The deformation monitoring data of both the dam body and the face slab of the concrete face rock-fill dam for Jilintai Hydropower Station I show that the max. settlement of the dam body is 77. 1 em with the max. settlement rate of 0. 948%. Through the relevant analysis, it is known that the settlement is mainly dominated by the impacts from both the filled materials and the impoundment of the reservoir, however, the vertical joint, peripheral joint, stress of reinforcement, flexual deformation of the concrete face slab are regularly changed, which are just coincided with the observed data of the internal deformation of the dam body. Those monitoring data can provide a basis for the analysis made on the deformation of the whole dam body.
