摘　　要：根据广义综合蓄热法的基本条件和适应范畴，本文研究了防冻剂混凝土在负温条件下，蓄热冷却过程的计算方法及吴氏解。实践表明：广义吴震东公式仍适用于负温防冻剂混凝土的冷却热工计算，但防冻剂水泥水化最终放热量Ｑ（ｏａ）及水泥水化速度系数ｍａ将影响其精确解。According to concrete's synthetic thermo-storage method's basic conditions and its if range of adaptabi9lity, it has in this article, studied the cooling calculation method and its solution of Wuzhcndong's formula under negative temperature. Practice has demonstrated that Wuzhendong's synthetic formula is atill applicable for cooling calculation of freeze-proof concrete under negative temperature. It is. however, that the freeze-proof cement's hydration ultimate thermal quantity Q(oa) and its hydration rate ma would eventually affect the accuracy of its solution.
