Temperature control and numerical analysis of massive concrete for construction of pier's base

针对大体积承台在混凝土浇筑过程中产生水化热,提出承台大体积混凝土施工温控的思路和工作流程,运用有限元软件MIDAS对大体积混凝土承台浇筑施工进行水化热温度场数值分析,介绍了承台大体积混凝土施工温控方案、模拟计算结果及施工过程控制计算,并与温度监测结果进行了对比分析。分析结果对类似工程施工具有一定的指导意义。

For the hydration heat generated by the massive concrete during the construction of the pier＇s base, the methods and operation processes of temperature control are presented in this article, using the finite element program MIDAS analyze the massive concrete temperature field of the hydration heat during the construction of the base. Besides, temperature control program for the construction of massive concrete, simulation of the calculation result and controlling calculation following the process of the construction compared with the data of temperature monitoring are introduced. The result of analysis and calculation could be a reference for the similar construction.
