| 摘 要： | 本文分析了流动化混凝土和凝固混凝土的流变变模型点。采用与拉式变换解答相容的求特解的方式对形象表达混凝土流变持征的Burgers模型和Hansen模型的本构关系进行了数学解析,分析了弹性流变行为。为实测确定混凝土的流变参数,定量描述混凝土的流变特征提供了依据。

| Abstract: | The paper has analysed the characteristics of rheological models of fresh concrete and harden concrete. The stress-strain relations for Burgers model and Hansen model, which can imaginarily express the rheological chacteritics of concrete, have been mathematically analysed by using the method of seeking particular solutions being consistency with the solution of Laplace transform, and the rheological behaviors of viscidity-elasticity aie also expounded, thus providing a scientific basis for determinig the rheological parameters and quantitatively describing the rheological characteristics of concrete. |
