摘　　要：为分析各类因素对公路高边坡稳定性的影响,采用有限元软件进行模拟分析。建模计算不同边坡设计参数和岩土物理力学参数下的边坡稳定性系数,通过对比分析得出:边坡设计参数方面坡高影响最显著,其次为边坡坡度,平台宽度影响最小;边坡岩土物理力学参数方面摩擦角的影响最显著,其次为黏聚力,岩土容重影响最小。通过对比分析确定各因素对边坡稳定性的影响,可为高边坡设计提供参考。The finite element software was used to simulate and analyze the influences of various factors on the stability of highway high slopes.The slope stability coefficients under different design parameters and geotechnical parameters were calculated by modeling.The comparative analysis showed that in terms of slope design parameters,the slope height had the most significant effect,followed by the slope gradient,and the platform width had the least effect;while in terms of geotechnical parameters,the friction angle had the most significant effect,followed by cohesive,and the geotechnical bulk weight had the least effect.Through the comparative analysis,the influence of each factor on the slope stability was determined,which can provide a reference for the design of high slopes.
