摘　　要：利用有限元程序对连续刚构桥梁承台大体积混凝土施工水化热进行计算,将计算结果与实测温度场进行比较分析,验证计算结果的正确性,为今后类似工程的水化热计算及温度控制提供参考。This paper calculates the hydration heat in construction of massive concrete for continuous steel bridge pile caps by means of the definite element program,compares the results of calculation with the measured temperature field,and verifies the correctness of the results of calculation.The analysis carried out by this paper provides the references for calculation of hydration heat and temperature control in future similar projects.
