摘要
层状结构岩体边坡的破坏模式主要为平面型滑移和倾倒破坏,是变形与强度各向异性的表现。文章应用节理化本构模型对露天矿顺层岩体结构边坡进行了FLAC数值模拟研究,结果表明,边坡体沿层塑性滑移带倾角与层面倾角基本一致,FLAC节理化本构模型可以为层状岩体的模拟提供一种有效的手段。
The failure mode of the layered structure rock slope would be a plane type slipping and toppling failure mainly and would be the different direction natural expression of the deformation and strength. With the application of the highly - jointed constitutive model, the paper had the FLAC numerical simulation study on the bedding rock structure slope in the surface mine. The results showed that the dip angle of the plastic slipping zone in the edgewise of the slope and the bedding tip angle were basically the same and the FLAC highly - jointed constitutive model could provide a effective means to simulate the bedding rock mass.
