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 .
In winter construction of concrete works, non-heating curing methods are mainly used. The key technology of this type of method is accurate thermal calculation. However, thermal calculation still widely uses Wu Zhendong’s theory. The whole formula established by Wu Zhendong’s theory can describe concrete under various conditions. The law of temperature and time changes, but because Wu Zhendong’s formula is more complicated, many scholars have made in-depth research and discussion on the simplified formula of Wu Zhendong. Based on this, the ideas, methods and methods for simplifying Wu Zhendong’s formula have been analyzed, and various simplified formulas and approximate formulas have been evaluated. The advantages and disadvantages.
