WebThe undrained shear strength (Su) of cohesive soils may also be correlated to results of in-situ testing such as Standard Penetration Test (SPT), Cone Penetrometer Test (CPT), … WebAs 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 process. In essence, the water content of the soil must remain constant during the shearing process. There are many projects where the undrained shear strength is used in the design analysis. WebShear strength = tf snf= normal stress at failure Uniaxial extension Tensile strength stf= 2tf Uniaxial compression Compressive strength scf= 2tf Note: Water has no strength tf= 0. Hence vertical and horizontal stresses are equal and the Mohr circle becomes a point. Strength criteria Back to Strength bait 3.3
