英文摘要 | Due to the stress redistribution after excavation, the pre-existent joints or cracks will deform and new cracks will initiate and propagate in surrounding rock, especially in the plastic zone. And differences, once cracks initiate and propagate in a certain area, exist when the equivalent continuum mechanics and non-continuum mechanics are used to analyze its mechanical response. A method is proposed in this paper to approximately simulate continuum before cracking and to change the potential joints to joints after cracking beginning which can approximately take the effects of cracking into consideration. And this method is explained, in detail, from its computation procedure, the determination of initial material parameters, the distribution of potential cracks and the failure criteria for the real and potential joints. Finally, two sets of numerical analyses are made to verify its effectiveness in approximately simulating continuum and the cracking process. |
