摘　　要：埋设冷却水管的大体积混凝土的温度场变化非常复杂,通过传统方法对其进行分析计算比较困难。依托永定新河特大桥承台的大体积混凝土工程,基于对大体积混凝土温度场构成因素的分析,利用大型有限元软件Midas/Civil,对桥梁承台大体积混凝土温度场进行预测,仿真模拟计算的温度场与实测值比较接近。The temperature field variation of massive concrete buried with cooling water pipe is very complicated.It is too difficult to analyze and calculate the above temperature field variation with the conventional method.According to the massive concrete project of Yongding New River huge bridge abutment,based on the analysis of the factors forming massive concrete temperature field,large finite element software Midas/Civil is applied to predict the massive concrete temperature field of bridge abutment.The simulated temperature filed is closer to the measured value.
