摘要
对混凝土的徐变及其机理进行了分析,从流变学方面阐述了徐变的一些流变模型,介绍了多种徐变理论及比较分析,进行了常应力及变应力作用下的徐变规律研究,并总结了徐变计算理论及计算方法的发展方向。
Creep and creep mechanism of concrete are analyzed, From viewpoint of rheology some rheologic models related to creep are presented. Comparative analysis is also carried out among several creep theories. Creep regularities under the actions of constant and variant stresses are studies. In the end the developmental direction of creep calculation theory and method is pointed out.
