WebThe most reliable method to estimate soil unit weight and shear strength is from laboratory testing of high-quality samples, however, there are also many methods to infer soil properties from in situ geotechnical tests (Mayne, 2007) and some from geophysical data (Vardy et al., 2024). 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.
