摘要
根据岩石流变学原理 ,对软岩巷道围岩破坏机理进行定性地分析 ,运用Burgers流变模型引入损伤变量 ,对圆形巷道粘弹性流变破坏规律进行定量的研究 。
Based on the rheological principle of rock, this paper analyses the surrounding rock mass failure mechanism qualitatively for soft rock tunnel. Using the rheological model of burgers and introducing the damage variable, the viscous elastic rheological regularities for the round tunnel were quantitatively researched. Decisional means of optimum support time was suggested for soft rock tunnel.
