文摘

Soil-Water-Retention-Curve influence on stability analysis is assessed. Unimodal and bimodal structured soils are taken into account. Clayey and bimodal soils are sensitive to the SWRC models. In sandy and unimodal soils, the choice of χ formulation is more important. The effects of SWRC and χ are significant within the soil moisture residual zone.
