| 摘 要： | 在以往有关节理模型实验和数值模拟的研究基础上,设计了几组含孔洞节理模型材料的压缩实验,并采用颗粒流软件Partide Flow Code(PFC2D)对模型实验过程进行数值模拟.以模型实验应力-应变曲线与数值模拟的曲线吻合作为PFC细观力学参数选取的准则,并利用获得的力学参数对含孔洞节理岩体破坏过程进行数值再现.分析了...

| Abstract: | Based on previous jointed model tests and numerical simulation studies,several groups of material compression tests were designed on joint models with holes,and model experimental processes were simulated with particle flow code software (PFC2D).Tallies of the stress-strain curve and numerical simulation curve were taken as selection criterion of PFC mesomechanics parameters in the model experiment.After that,the failure process of jointed rockmass with holes was simulated by the mesomechanics parameters to... |
