摘　　要：混凝土工程冬季施工主要采用非加热养护方法 ,这类方法的技术关键是精确的热工计算 ,而热工计算目前仍广泛采用吴震东理论 .按吴震东理论建立的整套公式可以描述混凝土在各种情况下温度时间变化规律 ,但由于吴震东公式较为复杂 ,许多学者对简化吴震东公式作了深入的研究和讨论 ,据此分析了简化吴震东公式的思路、途径与方法 ,并评价了各类简化公式和近似公式的优点与不足之处 .Non heating curing method is mainly adopted by concrete engineering in winter coustruction of our country.The technology crux of these methods is the accurate calculation in thermodynamics.At present,WU Zhen dong's therory is extensively adopted in accordance with insteady heat transfer.A group of formulae established according to WU Zhen dong theory may accurately describle temperature time variegated regulation in the thermose cooling course of concrete under all conditions. Because WU Zhen dong formula is too complicated,many researches have been made to simplify the calculation of this formula. This paper synthetically discusses the ideas,channels and methods put forword by all kinds of papers to simplify WU Zhen dong formula.It also gives comments on the advantages and deficiencies of the simplified formulae and approximate formulae .
