【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.更多还原
