Abstract

Soil is a heterogeneous medium and due to this, the parameters on which soil slope stability depends, are having high variability, which makes the analysis a complex problem. To take into account the variability in soil parameters, the current research approach is shifting from deterministic approach to probabilistic approach. This paper describes the application of three soft-computing techniques including multivariate adaptive regression spline (MARS), Gaussian process regression (GPR) and functional network (FN) to study the soil slope reliability based on slope stability. The stability of a soil slope of a given height depends on shear strength parameters c (cohesion), ϕ (angle of shearing resistance) and ϒ (unit weight), which are taken as input variables and Factor of Safety of soil slope (FOS) as the output. Also the model performance was assessed using various performance indices i.e. NS, RMSE, VAF, MAE, RSR, Bias Factor, PI, R2, Adj. R2, MAPE, GPI, LMI, U95, tstat and β. The results of the analyses showed that MARS model outperformed GPR and FN models. Therefore, MARS model can be used as a reliable soft computing technique for analyzing soil slope stability.
