| 摘 要： | 根据岩石加速蠕变阶段的力学特性，提出了一种非牛顿流体粘滞阻尼元件，将该阻尼元件与描述岩石减速蠕变和等速蠕变特性的传统模型结合，构成了新的综合流变力学模型，并应用于描述某大型水电工程坝区断层岩蠕变特性，效果良好。

| Abstract: | Rheological deformation is a basic mechanical property of rock. All rocks have acceleration creep property. Conventional rheologic models can't study accelerated creep property but deceleration creep and equal velocity creep properties of rock. A new rheological multiple model is put forward to study accelerated creep of rock, based on rheological properties of rock. The new rheological multiple model can contain the properties of many conventional rheological models. The good results are obtained when it is applied to analyze creep testing data of fault rock from the dam site of a large hydro-power station on Yalong River of China. |
