摘要
文章利用有限元数值模拟技术,计算在坡顶极限荷载作用下,以坡脚剪应力最大值之比K为评价指标,探讨岩质边坡各参数的变化对边坡稳定性的影响,并分析边坡稳定性对各参数的敏感程度,明确了凝聚力为边坡稳定的敏感参数,是边坡稳定性的控制因素;内摩擦角对边坡稳定性的影响也较明显。
This paper evaluates the influence of each parameter of rock slope on its stability based on the maximum shear stress rate K under top ultimate load with finite element numerical simulation technology,discusses the effect upon the slope stability by changes of each rock slope parameter and analyzes the sensitivity of slope stability to each parameter.It is indicated that cohesion is the sensitive parameter to slope stability as well as the control factor of slope stability.In addition,inner friction angle also has greater influence on slope stability.
