基于传热方程和傅里叶级数推导出一维混凝土内温度响应模型，并探讨其相关参数。通过现场试验，研究自然环境温度作用下的一维混凝土内温度响应规律，利用实测结果验证混凝土内温度响应模型的合理性；此外，利用实测数据验证求解混凝土传热系数方法的可行性。试验结果表明：所建立的一维混凝土内温度响应模型可表征自然环境温度作用下混凝土内温度响应规律，其理论拟合曲线与混凝土内实测温度值吻合较好；推导出的表面换热系数公式可以作为求解其值的新方法。

The interior temperature response model of one-dimension concrete was deduced from the heat trans-fer equation and Fourier series ,and its relevant parameters were also explored .The interior temperature re-sponse law of concrete under the action of temperatures in the natural environment was investigated through site tests ,and the rationality of the interior temperature response model was verified by measured results .In addition ,the trial method for solving heat transfer coefficients by measured data was studied .The results show as follow s :T he interior temperature response model of one-dimension concrete can be used to characterize the interior temperature response law of concrete under the action of temperatures in the natural environment and its theoretical fitting curve is consistent with the measured interior temperature of concrete ;the surface heat transfer coefficient formula derived from the heat transfer equation can be used as a novel solation .
