| 摘 要： | 本文研究了裂隙岩体非线性流变性态与裂隙损伤扩展过程的相互关系。文中通过裂隙损伤的流变断裂过程分析，推求具损伤演化耦合效应的岩体非线性流变状态方程，并与宏观唯象流变状态方程相比较，以寻求岩体非线性流变参数与裂隙损伤演化率的关系。最后，用某地下厂房原位试验洞的实测位移作了检验。

| Abstract: | in this paper,the underlying relationship between nonlinear rheological property of fissured rocks and damage development is studied.Based on the rheological fracturing process analysis for rock fissure damage,a nonlinear rheological state equation coupled with damage evolution is deduced for fissured rocks.The relationship between the nonlinear rheological parameters and the evolution rate of rock fissure damage is revealed by comparing the deduced rheological equation with the phenomenon-based rheological equation. Finally,the suggested model is checked by in-situ displacement measurements of an underground plant. |
