| 摘 要： | 围岩采用Mohr-Coulomb屈服准则、衬砌采用双线性本构模型,提出广义荷载作用下深埋圆形巷道中围岩和衬砌相互作用体系弹塑性解的解析表达式.在此基础上,研究了围岩的位移、位移灵敏度和塑性区等随广义荷载的变化规律.根据参数分析和实例计算得到:1)围岩或衬砌由弹性进入塑性,位移灵敏度将发生突变;2)位移灵敏度在弹性区和塑...

| Abstract: | In order to analyze the plastic evolution characteristic of rock-liner interaction for a deep circular tunnel,the elastic-plastic analytic solution for rock-liner interaction is developed under general loadings,in which the constitutive models of surrounding rock and the liner are the Mohr-Coulomb and bilinear model respectively.Based on the analytic expression,displacement,sensitivity of the displacement and plastic zone of surrounding rock varying with general loading are determined.The results of paramet... |
