摘要
论述了广义综合蓄热法混凝土蓄热冷却计算理论的简化计算出发点、理论依据及数学推导过程,并用简化公式计算了同一状态下蓄热的防冻剂砼Z-15及t-15值,用此简化公式与理论公式比较之,以求算广义综合蓄热法理论公式与简化公式计算误差限,通过哈尔滨卷烟厂综合大楼裸露面系数M=25的-10℃现浇防冻剂砼楼板实测,证明负温条件下广义吴震东公式简化计算公式可以使用。
It was described that the calculation theory of concrete thermal and cooling of general comprehensive thermos method was simplified,which was included starting point and the basis of theory as well as process of mathematics.It was shown that simplified formula can be calculated Z -15 and t -15 value of concrete with antifreezing agent in the same thermal condition.And then it was compared between simplified formula and theory formula.The former can be applicated by concreting floor of the office building of Harbin Cigarette Factory in bare faced coefficent of 25 at minus temperature in winter.
