Sensitivity analysis of slope stability based on orthogonal designs

Abstract

This study has investigated sensitivity of input parameters in stability analysis of earthen embankments to its factor of safety (Fs) using an experimental design approach. Computer experiments based on orthogonal designs were carried out to achieve efficient experiments, and a linear regression model was applied to analyze the results of the experiment. The Standardized Regression Coefficients (SRCs) obtained from the regression analysis was employed as indexes of the sensitivity of the input parameters to the F s. The results of the sensitivity analysis showed that the parameters about the geometry of embankments such as height and slope gradient are more sensitive to Fs, although the parameters about hydraulic characteristics of embankment materials are less sensitive to the Fs. In addition, interaction effects between input parameters were also analyzed, and its sensitivity to Fs was discussed.
