| Abstract: |
| The effect of the elliptical hole configuration on ultimate bearing capacity of rock masses was numerically studied to investigate the macroscopic mechanical properties of engineering rock mass in this paper.The relations between the elliptical hole configuration and the ultimate bearing capacity are ex-plained and the changing patterns of the induced acoustic emissions with elliptical hole configurations were also studied.The numerical simulations indicate that it is an effective method to study the macro-mechanical properties of engineering rock-masses,especially the ultimate bearing capacity of rock. |
