摘　　要：对现有的高性能混凝土的徐变计算模型进行了探讨和分析。将各种模型的徐变预测情况与实测值进行了比较,结果表明:编号W1的混凝土徐变要大于编号W2的混凝土徐变,B3模型理论计算值与试验值吻合较好,研究成果对实际工程中高性能混凝土结构的设计和施工提供了参考依据。The existing calculation models of creep of high performance concrete were discussed and ana-lyzed.Forecast models of creep condition were also compared with the measured values.The results show that the concrete creep of W1 is more than W2.The theoretical value of B3 model accord well with experi-mental value and the results of high performance concrete provide the reference to the practical engineering structure design and construction.
