Abstract: Accurate slope reliability analysis of unsaturated earth and rock dams requires a combination of spatial variability in soil shear strength parameters and hydraulic parameters.Such multi-parameter problems often result in dimensional catastrophes due to too many variables discrete from the random field, and traditional analysis methods are difficult to apply.For this reason, the multivariate adaptive regression spline（MARS） method based on sliced inverse regression（SIR） is proposed to analyze th... More
