大坝观测资料分析中谐波温度因子的改进及应用

首先从物理，数学的角度，论述了大坝观测资料回归计算模型中谐波温度因子的起源；之后，对其进行了改进，以考虑气温随机项的影响；最后通过对谐波温度因子系数的分析，给出了确定观测效应量滞后于气温时间的计算公式，实际应用表明，改进后不但计算精度有所提高，而且温度分量与时效分量分配也更加合理；同时，应用本文提出的方法可以比较精确地计算出观测效应应量滞后于气温的时间，这些都为正确评价大坝工作性态提供了良好的参考。

Improvement of Harmonic Wave Temperature Factor and Its Application to Analysis of Dam Monitoring Data

From the angle of physics and mathematics, discussed is the origination of the harmonic wave temperature factor in regression calculation model for dam monitoring data. In consideration of the random effect of temperature, the temperature factor is improved in this paper. Based on the analysis of the factor, a formula is given to calculate the time lag of the monitoring effect to the atmospheric temperature. Application shows that the improved factor may not only help improve the calculation precision, but also make the allocation of temperature component and time effect component more reasonable, providing a basis for the evaluation of dam operation behavior.
