摘要:
为研究圆形巷道围岩的稳定性，考虑了巷道围岩的损伤、剪胀特性以及中间主应力效应，建立了圆形巷道围岩弹塑性损伤力学模型，推导出圆形巷道围岩的弹塑性应力场和位移场解析解。研究结果表明：考虑损伤时围岩塑性区范围更大，所需支护阻力增长明显，塑性区位移明显增加；剪胀对位移场影响较大，对应力场影响较小，剪胀系数越大，需要提供的支护阻力就越大；随着中间主应力系数的增大，所需支护阻力降低，塑性区位移减小，最大位移减小幅度高达79.74%，不考虑中间主应力的强度准则偏于保守；考虑损伤、剪胀和中间主应力的新的位移解更加合理，研究成果为圆形巷道的设计支护提供了一定的理论基础和参考价值。
Abstract:
In order to study the stability of surrounding rock of circular roadway, a elasto-plastic damage mechanics model for surrounding rock of circular roadway was established considering the damage, shear dilation characteristic and intermediate principal stress effect of surrounding rock of roadway, and the analytical solutions of the elasto-plastic stress field and displacement field for surrounding rock of circular roadway were derived. The results showed that when considering the damage, the plastic area range of surrounding rock is larger, the required supporting resistance and the plastic area displacement increase significantly. The effect of shear dilation on the displacement field is larger, but the effect on the stress field is relatively small, and the greater the coefficient of shear dilation, the greater the required support resistance. With the increase of the intermediate principal stress coefficient, the required supporting resistance and the plastic area displacement decreases, and the maximum dis-placement is reduced by up to 79.74%, while the strength criterion without considering the intermediate principal stress is conservative. The new displacement solution considering the damage, shear dilation and intermediate principal stress is more reasonable, and the research results provide a theoretical basis and reference value for the design of circular roadway.
