高速铁路圆端形实体墩混凝土温度监测试验分析

Monitoring,Test and Analysis of Concrete Temperature for Round-ended Solid Pier

该文介绍了白龙河特大桥圆端形实体墩混凝土温度监测试验情况。在监测圆端形实体墩混凝土温度的基础上,分析其变化规律,确定圆端形实体墩混凝土施工的拆模时间,为现场实际施工提供了理论依据;并通过混凝土绝热温升、实际温峰值等理论计算,指出了理论计算与实际监测数据差距的原因。

The article introduces the monitoring test of concrete temperature of round-ended solid pier for Bailong River Bridge.On the basis of monitoring the concrete temperature of round-ended solid pier,the article analyzes its change rule and determines the dismantling template time of concrete construction for the round-ended solid pier in order to provide the theoretical basis for the filed practical construction.According to the theoretical calculation of adiabatic temperature rise and practical temperature peak value of the concrete,the article points out the reason of the data difference between the theoretical calculation and the practical monitoring.
