摘要
通过分析坝体混凝土温度过程线和温度场,得出混凝土水化热阶段是温度应力产生的主要阶段,通过冷却措施可以有效减小混凝土的热量对二次升温阶段和稳定阶段的影响,监测成果较好地证实了DTS的优越性和混凝土温度场变化的阶段性和规律性。
By analysis on the graph of concrete temperature and temperature field,conclusion was gotten that temperature stress mainly appeared during hydration heat.By cooling measures,the influence of hydration heat to the second temperature rising and stability can be lowered.What＇s more,the monitoring result proved the advantages of DTS as well as the stages and regularity of the change of concrete temperature field.
