混凝土水化热对冻结温度场影响的测试与数值分析

Test and Analysis of the Temperature of Ice Wall Affected by Heat of Concrete Hydration

摘要: 针对井筒内衬浇注混凝土水化热对冻结壁温度场影响的工程实际,对井筒浇注混凝土后的冻结壁温度场进行监测,并应用有限元数值方法进行比较分析。结果表明本文所建立的有限元分析模型可以比较准确的计算冻结壁温度场的变化规律,对工程实际具有指导意义。

Abstract: This paper focuses on studies of distribution of temperature filed of ice wall affected by heat of concrete hydration by testing and the FEM methods.The solution of simulation analysis is compared with testing result,which illustrates that models are correct and applicable to engineering.
