混凝土蓄热法在特定条件下是冬期施工中最为简便而又经济的施工方法。过去在计算时采用传统的斯氏公式。事实上,被奉为经典的斯氏公式由于一直无人验证,其误差较大,不能使用。作者于1981年10月、1983年10月在《建筑技术》上先后发表了《非大体积混凝土冷却计算理论的研究》和《非大体积混凝土蓄热计算和施工要求》两文,提出了“非大体积混凝土蓄热微分方程式”,从而解得了精确度较高的一整套蓄热计算公式。本文在以上基础上对计算公式加以讨论分析,简
The concrete heat storage method is the simplest and most economical construction method in winter construction under certain conditions. In the past, the traditional Smith’s formula was used in the calculation. As a matter of fact, the classical formula of Stephen’s formula has been untested and its error is too large to be used. In October 1981 and October 1983, the author published the “Study on the Theory of Non-massive Concrete Cooling Calculation” and the “Non-massive Concrete Thermal Storage Calculation and Construction Requirements” in “Architecture Technology”, and proposed “ Non-massive concrete heat storage differential equations”, thus solving a complete set of heat storage calculation formula with higher accuracy. This article discusses and analyzes the formulas on the above basis.
