中文摘要：

Preisach-Mayergoyz（PM）空间中的滞回细观单元对外力或温度是否响应对某些单元来讲存在着不确定性,这将导致循环加载时滞回圈的不稳定。外载频率和温度不同,岩石中微细观结构参与对宏观外力和温度响应的转换概率也不同。通过单轴和三轴循环加载实验可得：随频率增高,微细观结构对外力响应的转换概率减小,自适应调整时间缩短,滞回圈越容易趋于稳定;随温度不断升高,微细观结构对温度响应的转换概率增大,自适应调整的时间增长,滞回圈散开趋于不稳定。因此,降低频率与升高温度都将导致滞回圈趋于不稳定,这进一步说明,降低频率与升高温度是等效的,从原理上证明了饱和岩石的时温等效性。这一结论对大型地下工程或深埋核废料和CO2的储藏是很有意义的。

英文摘要：

　In Preisach-Mayergoyz（PM） space,whether the hysteretic mesoswpic units（HMU） response to the applied forces and temperature or not is uncertain,these responses will lead to the instability of hysterisis loops of rocks under cycle loading.The transformation probability of meso structure varies with the external forces and temperature.It could be concluded from the experiments of the uniaxial compression and conventional triaxial compression that when the frequency turns higher,the transformation probability of meso structure reduces;the times of the self-consistent adjustment become shorter and the hysteresis loops tend to be stable more easily.Meanwhile,with the increase of temperature,the transformation probability of meso structure increasest;he times of the self-consistent adjustment become longer and the hysteresis loops disperse and tend to be unstable with the increasing of the strain.Thus,reducing frequency and raising temperature could lead to the same result,i.e.the instability of hysteresis loops.All these might show that reducing frequency and raising temperature are equivalent.These results of the equivalence of the frequency/time and the temperature are meaningful to the large-scale underground project and the deep disposal of nuclear waste and CO2.
