摘　　要：根据广义综合蓄热法原理,研究负温防冻剂砼在其硬化温度允许条件下所需的保温条件,并给出其计算方法,提出广义综合蓄热法负温防冻剂砼硬化的保险区、临界区及危险控制区与计算方程的临界限。According to the theory of general comprehensive thermos method, we investigated the thermal conditions of concreting with antifreezing admixture hardness at minus temperature, and then gave some calculation methods that include safe temperatue zone and critical temperature zone as well as dangerous control temperature zone. In addition, we also put forward a boundary of calculation equation.
