| 摘 要： | 进行了某大桥用高性能混凝土的徐变试验,分析了徐变、徐变度及徐变系数随龄期的变化关系,并采用指数衰减统计模型、非等间距GM(1,1)模型和DGM(2,1)模型对后期徐变变形进行了预测,预测结果可作为徐变控制的参考依据。

| Abstract: | The experimental study of creep of high performance concrete to be used for a bridge was made.The relations of the creep deformation,creep degree and creep coefficients varying with the concrete age development were analyzed and the latter period creep deformation was also predicted,using the exponential decay statistics model and grey system method of GM(1,1) and DGM(2,1) models.The results of predication as provided in the paper may serve as the reference basis for controlling of the creep. |
