摘要(中) 本文利用PFC3D模擬互層岩體單壓及三軸試驗之力學行為,並觀察岩石內部的裂縫發展過程及破壞模態。此外,本文亦針對PFC3D之微觀參數,進行宏觀岩體力學行為之參數研究。模擬結果顯示,PFC3D模擬互層岩體之力學行為與田永銘等人(1996)實驗相符;於圍壓=0 MPa,強度異向性顯示為「肩膀型」,而圍壓=2.5、5.0及10 MPa時,岩體強度則會隨著傾角增加而增加。最後,本文將互層岩體破壞模態分為三類,分別為(1)滑動破壞、(2)張裂破壞及(3)剪力破壞。

摘要(英) This paper used PFC3D to simulate interlayered rocks mechanical behaviors under uniaxial compressive test and triaxial compressive test, and observed fracture propagations. In addition, this paper also investigated micro-parametric studies for macro-mechanical behaviors. The simulation results show that the anisotropic mechanical behaviors from numerical simulations are compared well with Tien et al. (1996); the strengths anisotropy shows “the shoulder type” at confining pressure (C.P.) = 0 MPa. But at C.P. = 2.5, 5.0, 10 MPa, the strengths of interlayered rocks increase with increasing inclination angle θ. Finally, this paper proposed three failure modes, (1) sliding failure, (2) tensile split failure, and (3) shear failure.
