采用正交极差分析方法,在考虑边坡稳定性各影响因素间交互作用的前提下,克服了传统计算方法大量试算的繁琐,定量给出了各因素对边坡稳定性影响程度的主次关系,并绘制出各影响因素与边坡安全系数间的关系曲线,根据安全系数随各影响因素变化的趋势,可为露天边坡结构参数的优化设计提供参考依据,并能指导生产,确保边坡的安全。 By using the method of orthogonal range analysis, taking into account the interaction between various factors of slope stability, this paper overcomes the cumbersome calculation of a large number of traditional calculation methods and quantitatively gives out the main factors influencing the slope stability According to the changing tendency of safety factor with each influencing factor, it can provide a reference for the optimal design of structural parameters of open slope and can guide the production to ensure Slope safety.
