As the name implies, the undrained shear strength s u refers to a shear condition where water does not enter or leave the cohesive soil during the shearing …
This term describes a type of shear strength in soil mechanics as distinct from drained strength. Conceptually, there is no such thing as the undrained strength of a soil. It depends on a number of factors, the main ones being: • Orientation of stresses • Stress path WebOct 21, 2024 · Undrained tests can be used to obtain effective stress (and total stress) parameters if you measure the pore-water pressure. This is because you are able to calculate what the effective stresses are, so can plot the effective stress path.
WebApr 8, 2024 · The undrained shear strength (s u) is indeed a vital parameter governing the strength and stability of the soil at its failure state, which is ... the behaviors (i.e., Δσ 1 and Δε a) of the sample obtained from the third loading cycle are adopted to calculate the dynamic modulus.
