摘　　要：以某黄河大桥第40号和41号主塔墩承台为例，采用有限元法模拟三维瞬态温度场，考虑施工过程和温控措施的影响，选取了计算模型，并介绍了计算原理，通过分析得到了大体积承台混凝土内部温度场分布规律，得出了理论计算分析与实测结果符合较好的结果。Taking the No. 40 and 41 of the main tower pier cap on one yellow river bridge as an example, Considering the impact of construction and temperature control, this article find out the distributing orderliness of temperature field inside the mass pile cap concrete and the accordance of theoretical calculations and measured results by simulating 3-D transient temperature field with finite element method. It also selected calculation model and introduced the principle of the calculation.
