摘要
为了更准确地分析大坝水平位移的变化规律,在建立坝体水平位移的统计模型时,采用温度周期项和温度实测值对温度分量进行建模,并将模型应用于李家峡拱坝进行对比分析.结果表明,利用温度周期项建立的模型,模型计算值与实测值拟合较好,模型能够很好地反映出大坝水平位移的变化规律.
In order to more accurately analyze the variation of horizontal displacement of dams,a statistical model was established.The temperature component of the horizontal displacement should be considered from two aspects of the temperature period item and the observed temperature data.The proposed regression model was applied in Lijiaxia Arch Dam.The results show that the introduction of the temperature period item into the model leads to an agreement between the calculated and observed values,and the model can well reflect the variation of horizontal displacement of the dam.
