本文提出了一种在复合膨胀岩体中考虑其耦合流变性态和渗流效应以设计有压隧洞衬砌的有限元方法。采用粘弹塑性计算模型可以描述围岩—支护系统应力和位移随时间的变化,使对所设计结构的受力机理能有更好的理解。
This paper presents a finite element method for designing pressure tunnel linings considering the coupled rheological and seepage effects in composite expansive rock masses. The viscoelastic-plastic calculation model can be used to describe the changes in stress and displacement of the surrounding rock-supporting system over time, enabling a better understanding of the stress mechanism of the designed structure.
