摘要
为准确地分析双支墩大头坝垂直位移变化规律,在建立坝体垂直位移统计模型时,采用温度周期项、气温实测值和混凝土温实测值对于温度分量进行建模,并对模型进行对比分析。结果表明:采用混凝土温实测值建立的模型的计算结果和实测值拟合较好,能更好地反映出大坝垂直位移变化规律。
In order to analyze more accurately tress dam, the temperature component should the changing rules of vertical displacement of massive - head double butbe considered from the temperature periodic item, the temperature measured data and the measured concrete temperature when building the statistical model and the models are comparatively analyzed. The results indicate that the calculation result of the model built by the measured concrete temperature fits the measured data better and can better reflect the changing rules of the dam vertical displacement.
