Undrained shear strength calculation
WebJan 1, 2001 · This paper discusses a method for calculating the “true” undrained strength ratio, ( cu/p) ss, of normally consolidated clays measured in a simple shear test. The proposed method assumes that the directions of the principal stress axes during the simple shear test are expressed by the relation proposed by Oda and Konishi (1974). WebThe undrained shear strength (Su) can be estimated for low plasticity clays (PI ≤ 10) and medium to high plasticity clays (11 ≤ PI ≤ 40) using the relationship developed by …
