在前人的研究基础上提出了一种新的非定常参数的岩石蠕变模型,该模型由一个牛顿体和一个类似于开关的SO元件并联后与一个广义Kelvin体串联,通过SO元件的作用,新模型可以在Burgers模型与广义Kelvin模型之间切换,并将Burgers模型中牛顿体的粘滞系数η1看成与时间有关的非定常参数,使得模型不仅可以反映稳态蠕变过程也可以反映加速蠕变过程.
Component-combined model is one of the component-combined linear models can' t describe the non-linear component models are main methods to describe the creep of rocks. Traditional damage character of rock creeping. To solve this problem, and good effects are received. A new non-stationary parameters creep model of rocks is presented. This model consists of a general Kelvin model and a parallel model connected with a Newton component and an SO component like a switch key. Because of the action of SO component, the new model can switch to Burgers model or general Kelvin model to describe the stationary stage of creep. Moreover, if let η1 be a non-stationary parameter of time, the problem that Burgers model can't describe the damage process is successfully solved .
