摘要
恶劣的气候条件对混凝土质量影响很大,考虑到核电站结构的重要性,有必要以瞬态热传导方程和水化热模型为基础,建立三维有限元模型进行分析。本文以恰希玛三期工程为对象,通过对大体积混凝土的温度场进行计算和分析,得出其温度场分布规律,防止有害温度裂缝产生,为类似核电站大体积混凝土设计与施工提供参考。
The concrete quality is greatly affected by abominable weather,and the quality of nuclear power plant structure is very important,so basing on instantaneous heat exchange equation,hydration heat model and established three-dimensional finite element model,it is necessary to calculate and analysis the temperature field of basement slab mass concrete in chashma nuclear power plant project unit 3.It will get the distributing rule of temperature field of mass concrete,prevent the nocuousnes temperature crack,and offer the theory gist of analogy nuclear power plant mass concrete structure analysis.
