摘要There are many factors affecting the stability of cut and fill multistage slopes, and these factors exert different degrees of influence on slope stability. The grey incidence analysis method can be used to evaluate the sensitivity of these factors. To overcome the shortcomings of the grey incidence analysis model used in previous sensitivity analysis studies on the factors influencing slope stability, this study improved the dimensionless processing method and resolution coefficient value. Considering that the importance of each influencing factor is different, the vector resemblance degree theory was applied to determine the weight of each influencing factor. Finally, based on an actual cut and fill multistage slope, the sensitivity of the factors affecting stability was analyzed according to the improved grey incidence analysis theory. The results revealed that the unloading platform width, cohesion force, and internal friction angle are most sensitive to the stability of the cut and fill multistage slope. The step height, slope width, and slope height are slightly sensitive, while the soil unit weight, seismic peak acceleration, and slope ratio are the least sensitive.
