| 英文摘要 | This paper studies the stability of jointed rock slopes by using our improved three-dimensional discrete element methods (dem) and physical modeling. results show that the dem can simulate all failure modes of rock slopes with different joint configurations. the stress in each rock block is not homogeneous and blocks rotate in failure development. failure modes depend on the configuration of joints. toppling failure is observed for the slope with straight joints and sliding failure is observed for the slope with staged joints. the dem results are also compared with those of limit equilibrium method (lem). without considering the joints in rock masses, the lem predicts much higher factor of safety than physical modeling and dem. the failure mode and factor of safety predicted by the dem are in good agreement with laboratory tests for any jointed rock slope. |
