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。 Most of the geotechnical parameters that affect the stability of slope have the characteristics of uncertainty such as randomness, fuzziness and variability, therefore, the uncertainty analysis model needs to be introduced for analysis. Based on the comprehensive analysis of interval parameters of geotechnical parameters, this paper applies the interval analysis model to the stability analysis of slope. By referring to the idea of ​​interval math, the minimum safety factor interval of slope is deduced by interval limit equilibrium method, and based on which, the non-probabilistic reliability analysis of slope is carried out.
