中文摘要：
改进了混凝土大坝施工期应变统计模型,采用3个指数函数累加来表示时效分量,该时效分量表达式可描述任意收敛型的时效分量。对西南地区某建设中混凝土坝的实测应变资料分析结果表明,所提出的改进统计模型拟合精度较高,可用于对施工期的应变资料进行预处理。
英文摘要：
The statistical model for strain of concrete dams during the construction period is improved. Three cumulative exponential functions are used to represent the time component, and the expression for the time component can describe the time component of any convergence. The modified model is employed to analyze the measured strain data of a concrete dam under construction in southwestern region of China. The results show that the proposed model has high precision, and it can be used for the pretreatment of strain data of concrete dams during the construction period.
