蠕变试验中流变模型辨识及参数确定

Distinction of Rheological Model and Determination of Parameters on Creep Tests

对岩石流变性态作了全面分析，提出了能描述岩石最复杂流变性态的流变模型，介绍了用不同应力水平下的蠕变试验加载卸载曲线辨识各种流变模型及其参数的方法．

This paper analyses the rheological properties of rock in detail.The rheological model describing maximum complicated rheological properties of rock is proposed. The relationship between this model and all other models used in rockis given. The method to distinguish various rheological models and determinemodel parameters with loading and unloading creep test curves under different stress levels is introduced.
