In the proceedings of: GeoVirtual 2020: 73rd Canadian Geotechnical ConferenceABSTRACT: A variety of geotechnical projects are initiated with unsupported vertical cuts in vadose zone. In this case, it is crucial to consider the contribution of soil suction in analyzing the stability of unsupported vertical cuts. Soil-Water Characteristic Curve (SWCC) is a main tool that can be used to estimate the variation of shear strength of soil with respect to soil suction. SWCC can be obtained using different fitting models based on experimental data. In this study, a series of numerical analyses are carried out to investigate the influence of SWCCs obtained using different SWCC fit models (i.e. Brooks & Corey, van Genuchten, and Fredlund & Xing models) on the safe height of unsupported vertical cuts in sandy soil. The analysis results showed that the safe heights estimated with the van Genuchten model are most reasonable for various levels of ground water tables.
