摘要
文中基于Hoek-Brown破坏准则,通过数值计算揭示岩质边坡开挖过程中的变形规律及其影响因素。结果表明,完整岩质边坡在开挖过程中整体失稳风险较小,但局部呈现明显凸起趋势;其中开挖间隔时间的不同对边坡局部变形有一定影响,而锚固结构对局部变形和整体稳定性均有较为明显的影响。
The deformation law and influencing factors of rock slope during excavation are revealed by numerical calculation.The results show that the overall risk of rock slope instability is small,but the local part shows obvious convex trend;the different excavation intervals has a certain impact on the local deformation of the slope,while the anchorage structure has a more obvious impact on the local deformation and overall stability.
