边坡稳定性影响因素的敏感性正交极差分析

Orthogonal Experiment Range Analysis of Sensitivity of Factors Influencing Slope Stability

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。

Considering the interaction among the influence factors of slope stability, the importance of various factors influencing slope stability were quantitatively determined by orthogonal experiment range analysis, and the relation curves between various factors and safety coefficient of slope were drawn. This method avoided a large amount of calcula- tions caused by traditional calculation method. The trend of the safety coefficient changing with the influencing factors can provide reference for optimization design of open-pit slope structure parameters and guide the production to en- sure the safety of slope.
