摘要
根据有关岩石力学试验结果，提出了以对数函数描述岩石蠕变的本构模型．借此对地下圆形隧道围岩稳定性进行了力学分析，探讨了人工支护结构与围岩相互作用的关系，导出了描述其变化规律的特征方程，由此而得出了一些有益的结论．
Based on some rock testing results in laboratory, a logarithmic law is presented as a constitutive model to describe rock creep. With the model, the underground tunnel which is excavated at great depth beneath ground is discussed by taking rock behaviour as a viscoelastic body. The linear support is assumed.And the interaction between rock and support is analysed. By means of mechanical analysis underground tunnel stability is formulated in a governingequation which can reasonably explain some phenomena happening in the tunnel.
