摘要

伯格斯（Burgers）模型适合用来描述岩石第三期以前的蠕变曲线。为了描述整个蠕变过程，可以考虑力学参数的时间效应，用非定常黏壶替换Burgers模型中的定常黏壶，给出一种非定常Burgers模型，并推导出它的蠕变柔量，实验数据拟合表明该模型能较好地反映岩石的试验曲线

Abstract

The Burgers model could only describe the behavior of rock material before the third creep-phase. The viscous components of Burgers model are replaced by non-stationary viscous components. The modified Burgers model is also called as non-stationary Burgers model; and its creep compliance is obtained. Comparison between the results obtained from non-stationary Burgers model and the experiment shows that this model can well describe the initial attenuation creep phase

the stabilization creep phase and the speedup creep phase of the creep curve
