摘　　要：通过3种徐变预测模型计算值与试验实测值的比较,分析了各模型在泵送高强混凝土徐变预测中的适用性;采用修正参数修正B3模型,以此来提高该模型的预测精度.最后针对考虑徐变效应结构分析中徐变预测模型的选用提出了一些建议.Applicability of 3 kinds of prediction model in prediction of concrete creep was analyzed through comparison between calculation value and experiment data. And also B3 prediction model for creep was updated by changing some parameters of the model to enhance the accuracy of prediction. Finally some useful suggestions were made for the selection of creep prediction model in structural design and analysis.
