摘　　要：结合某超高层结构混凝土收缩徐变实测数据,利用B3变异系数法考察了CEB-FIP模型、ACI209R-92模型以及GL2 000模型对于高强、高流动性混凝土收缩与徐变的预测准确程度。分析结果表明,对于高强、高流动性混凝土,ACI209R-92模型更适于预测徐变,而GL2000模型更适于预测收缩。Combined with the measured data of shrinkage and creep of concrete used in a super high-rise structure, the accuracy of the CEB-FIP model, ACI209R-92 model and GL2000 model for the prediction of shrinkage and creep of high-strength and high-flow concrete is investigated by using the B3 coefficient of variation method. The results show that for high strength and high fluidity concrete, ACI209R-92 model is best suited for predicting creep and GL2000 model for shrinkage.
