基于区间不确定分析方法的边坡稳定性分析

INTERVAL ANALYSIS MODEL OF GEOMATERIAL PARAMETERS FOR UNCERTAINTIES IN SLOPE STABILITY ASSESMENT

摘要: 影响边坡稳定性的岩土参数大多具有随机性、模糊性和可变性等不确定性的特点,因此,需要引入不确定性分析模型进行分析。本文在综合分析岩土参数区间性的基础上,将区间分析模型应用于边坡的稳定性分析。通过引用区间数学的思想,运用区间极限平衡法推导出边坡最小安全系数区间,并在此基础上对边坡进行非概率可靠度分析。

Abstract: This paper is based on a comprehensive analysis of geomaterials parameters. It introduces the interval analysis model for stability assesment of slopes. By referring interval mathematics idea, the interval limited equilibrium method is used to derive the interval minimum safety factor of slopes. Based on this foundation, the paper carries out the non-probabilistic reliability analysis of slope stabilities.
