通过分析岩石破坏过程中孔隙率变化规律,将其与蠕变过程中应变率变化规律联系起来,根据线性相关的假设导出了蠕变变形与孔隙率的关系式。本文基于孔隙率变化而建立的三阶段蠕变方程,为岩石蠕变模型研究提供了一个新的思路和方向。 By analyzing the variation law of porosity during the process of rock failure and correlating it with the variation of strain rate during creep, the relationship between creep deformation and porosity is derived based on the linear correlation assumption. The three-stage creep equation established in this paper based on the porosity change provides a new idea and direction for the study of rock creep model.
