摘要:

分析了Bazant混凝土固化徐变理论的特点与适用条件，利用砂牌工程碾压压混凝土材料徐变试验资料计算了老化粘弹性相徐变，非老化粘弹性相徐变，粘性流动相徐变（不可恢复徐变）的组成比例，从而验证了将该理论应用于碾压混凝土材料的合理性。

Abstract:

Among a number of compliance functions of concrete creep, power exponential function has been selected to be as model code by the State Electric Company and Water Resource Minister of China recently. Because of that power exponential function involves so many parameters and ignores the non reverse creep of concrete, the precision is quite limited in mathematical calculation, especial in simulating the constructing processes of mass concrete. This paper analyzed the characters of Bazant's solidification theory for concrete creep and its condition in application, and certifies its rationality when it is used in RCC concrete with actual testing information.
