摘　　要：北京市某工程冬期施工中应用电伴热对混凝土进行保温养护,利用相关数据进行强度-成熟度曲线公式的回归拟合,对不同部位的混凝土强度成熟度进行计算,找出成熟度和强度之间的关系并与实际强度进行对比,验证了计算的准确性。During winter construction of a project in Beijing, electric tracing was adopted for insulated concrete curing. Related data were used for regression fit analysis of strength-maturity curve formula, to calculate the concrete strength and maturity at different positions. The relation between concrete maturity and strength was found out and was compared with practical strength to verity the calculation accuracy.

关 键 词：冬期施工 混凝土强度 电伴热成熟度
