摘　　要：研究2008奥运工程——国家体育场工程中大体积混凝土的凝固温度问题,采用有限元法分析混凝土构件凝固中温度场的变化规律,并考虑实际工程中的多种边界条件、气候条件的影响.本研究对于混凝土凝固温度的控制和防护具有重要的指导意义.This paper investigates the consolidation temperature of large-volume concrete used in the stadium which was constructed for the 2008 summer Olympic Games hold in Beijing. The variation and distribution of the temperature during consolidation of the concrete are studied by finite element method. The real boundary conditions of temperature field and climate effect are considered in modelling the practical construction environment.
