| 摘 要： | 软岩巷道围岩体具有明显的大变形、大地压、长时间持续流变的特性,这使得软岩巷道尤其是衬砌支护之后巷道的大变形研究及控制机理成为复杂的力学问题.本文利用围岩与支护的接触条件,运用弹一黏塑性理论研究了软岩巷道问题,并探讨了巷道位移、支护阻力与黏性系数和时间的关系.研究结果显示:黏性系数越小,时间对于软岩巷道变形影响越大;增大围岩的黏性系数将会减小巷道的变形.

| Abstract: | The soft rock tunnel has many particular properties,such as large deformation,great ground pressure,and continuous long time rheology,thus making the study of large deformation and supporting technique of tunnel become a complex problem.According to the contact condition of wall rock and lining and based on the elasto-viscoplastic theory,problems of tunnel deformation and the lining resistance,and their relation with viscosity coefficient and time are discussed.The results show that the tunnel deformation i... |
