WebMar 5, 2024 · 2.4.7.3. Drained Shear Strength. The drained shear strength is the shear strength of the soil when pore fluid pressures, generated during the course of shearing the soil, are able to dissipate during shearing. It also applies where no pore water exists in the soil (the soil is dry) and hence pore fluid pressures are negligible. WebThe FSS is used to model the shear strength of shallow slope soils because it represents the shear strength remaining after the effects of overconsolidation, compaction, desiccation, or other strengthening processes have been removed because of wet-dry cycles, applied shear stresses, stress relief, progressive deformation or failure, swelling, freeze-thaw cycles, …
