| 摘 要： | 对隧道围岩与初衬之间的相互作用进行了研究,并对二次衬砌前的围岩和初衬中应力与位移及其释放进行了计算分析.首先利用线性黏弹性理论,导出了隧道开挖后围岩和初衬中的应力与位移;然后选取Maxwell和Poyting-Thomson三参数固体流变模型模拟围岩,研究了隧道围岩与初衬之间的相互作用;最后结合公路隧道施工,计算了二次...

| Abstract: | In this paper,the interaction between tunnel surrounding rock and early support is studied,stress and displacement in tunnel surrounding rock and early support before second lining are made,and their release are calculated.Firstly,the stress and displacement in tunnel surrounding rock and early support are derived by using linear viscoelastic theory.Then,the interaction between tunnel surrounding rock and early support is studied by surrounding rock to be simulated with Maxwell and Poyting-Thomson three-par... |
