A Novel Radial Basis Function Approach for Infiltration-Induced Landslides in Unsaturated Soils

In this article, the modeling of infiltration--induced landslides, in unsaturated soils using radial basis function (RBF) method, is presented. A novel approach based on RBF method proposed to deal with nonlinear hydrological process zone. The first adopted for curve fitting build representation soil water characteristic (SWCC) that corresponds best estimate relationship between volumetric content and matric suction. meshless then applied solve Richards equation infiltration boundary conditions. Additionally, fictitious time integration tackling nonlinearity. To model stability landslide, analysis infinite slope coupled considering fluctuation transient pore pressure developed. validation accomplished by comparing exact solutions. comparative factor safety Gardner model, van Genuchten provided. Results illustrate advantageous reconstructing SWCC better estimation than conventional parametric models. We also found computed factors significantly depend SWCC. Finally, landslides highly affected potential during process.
