中文摘要：
将强度折减有限元法与ABAQUS软件相结合,对含有软弱结构面的岩石边坡进行了模拟,利用软件的后处理功能显示塑性应变和塑性区的开展情况,以此作为含软弱结构面岩坡失稳的评价依据.通过分析岩坡中软弱结构面的贯通率、几何位置、结构面间的岩桥长度等因素对边坡破坏模式及安全系数大小的影响,证明了软弱结构面是控制岩质边坡破坏的主要因素.算例的模拟分析说明,ABAQUS软件能够较为准确地预测含软弱结构面的岩质边坡潜在破坏面的形状位置,对于复杂的岩质边坡的稳定性分析具有是实用性.
英文摘要：
Combined the strength reduction finite element method with ABAQUS software, stability analysis of rock slope with weak structure planes were simulated in this paper. The post-processing function can display the development condition of the plastic zone, which is the criterion for instability of the slope. Analysis of the position of weak structure plane in the slope and the length of rock bridge between different structure planes prove that the weak structure plane plays a key role in the instability of rock slope. Simulation results shown that ABAQUS can accurately predict the shape and position of the potential failure surface.
