摘要
采用三维瞬态温度场,建立大体积混凝土温度场有限元计算模型,研究了温度场在承台内部分布和随时间变化规律,并制订了一套完整的温度与裂缝控制方案,实践证明,采取控制措施后,施工效果良好。
With the theory of three-dimensional transient state temperature fields, a finite element model for calculating temperature fields of mass concrete is created. The laws of distribution and time-dependent variations of the temperature fields inside the pile caps are investigated. And a set of complete temperatures and crack control plans has been drawn up, the .effect of which proved to be good in practice.
