摘要
以岩滩水电站混凝土重力坝为例,对其垂直位移监测资料的变化规律进行了定性、定量分析,提出了在回归建模时应从温度周期项和温度实测资料两方面考虑温度分量。据2008年的拟合效果比较可知,坝体垂直位移变化规律正常。
Taking the concrete gravity dam of Yantan Hydropower Station for an example, this paper analyzes the change rule of vertical displacement monitoring data. The temperature component of the vertical displacement should be considered from two aspects of the temperature periodic item and the temperature measured data when building regression model. According to the fitting results by the data in 2008 year. it shows that the change rule of the dam vertical displacement is normal.
