Based on elasto-viscoplastic theory of Perzyna and strain energy theory and 3D yield criterion considering the effect of intermediate principal stress, a mesoscopic coupled elasto-viscoplastic-damage model is developed in order to explore the intermediate principal stress effect on the time-dependent behavior of deep hard rock in excavation damage zone. The model is implemented in a software for engineering rockmass fracturing process (CASRock). By comparing modeling results with experimental results, the model and the code are validated. Furthermore, the time-dependent behaviour of #1 laboratory of CJPL-II project is simulated, and the time-dependent fracture process of hard rock in excavation damage zones under different intermediate principal stresses are investigated. The results show that the time-dependent fracture behavior of hard rock exhibits an obvious interval effect of intermediate principal stress. It is found that the interval effect of the intermediate principal stress is affected by time through the isochronous curve clusters of the total viscoplastic strain and the intermediate principal stress. Finally, the existence of the excavation damage zone can promote the development of time-dependent fracture of its internal surrounding rock, thereby expanding the scope of the plastic zone.

为探究中间主应力对深部硬岩开挖损伤区时效行为的影响,基于Perzyna弹粘塑性理论和应变能理论及考虑中间主应力的三维屈服准则,建立了硬岩蠕变全过程的粘塑性损伤耦合本构模型,并将其嵌入到工程岩体破裂过程分析软件(CASRock)中,通过比较模拟结果与试验结果,验证了模型和程序的有效性。进一步模拟了锦屏地下实验室二期工程#1实验室的时效行为,并探究了不同中间主应力作用下硬岩开挖损伤区的时效破裂过程,发现硬岩的时效破裂行为表现出明显的中间主应力区间效应;通过总粘塑性应变与中间主应力的等时曲线簇发现中间主应力的区间效应受时间影响;开挖损伤区的存在能促进其内部围岩时效破裂发展,从而扩大塑性区的范围。

为探究中间主应力对深部硬岩开挖损伤区时效行为的影响,基于Perzyna弹粘塑性理论和应变能理论及考虑中间主应力的三维屈服准则,建立了硬岩蠕变全过程的粘塑性损伤耦合本构模型,并将其嵌入到工程岩体破裂过程分析软件(CASRock)中,通过比较模拟结果与试验结果,验证了模型和程序的有效性。进一步模拟了锦屏地下实验室二期工程#1实验室的时效行为,并探究了不同中间主应力作用下硬岩开挖损伤区的时效破裂过程,发现硬岩的时效破裂行为表现出明显的中间主应力区间效应;通过总粘塑性应变与中间主应力的等时曲线簇发现中间主应力的区间效应受时间影响;开挖损伤区的存在能促进其内部围岩时效破裂发展,从而扩大塑性区的范围。

Based on elasto-viscoplastic theory of Perzyna and strain energy theory and 3D yield criterion considering the effect of intermediate principal stress, a mesoscopic coupled elasto-viscoplastic-damage model is developed in order to explore the intermediate principal stress effect on the time-dependent behavior of deep hard rock in excavation damage zone. The model is implemented in a software for engineering rockmass fracturing process (CASRock). By comparing modeling results with experimental results, the model and the code are validated. Furthermore, the time-dependent behaviour of #1 laboratory of CJPL-II project is simulated, and the time-dependent fracture process of hard rock in excavation damage zones under different intermediate principal stresses are investigated. The results show that the time-dependent fracture behavior of hard rock exhibits an obvious interval effect of intermediate principal stress. It is found that the interval effect of the intermediate principal stress is affected by time through the isochronous curve clusters of the total viscoplastic strain and the intermediate principal stress. Finally, the existence of the excavation damage zone can promote the development of time-dependent fracture of its internal surrounding rock, thereby expanding the scope of the plastic zone.
