Undrained shear strength from cone penetration test

qc is the cone tip resistance, Nk is the empirical cone factor, Su is the undrained shear strength, and a yO is the total vertical stress at the depth of penetration. The wide scatter in the empirical and theoretical Nt values presented in the literature shows that no single value of Nk covers all

Interpretation of Cone Penetration Tests in Cohesive Soils

An important use of cone resistance is in the design of pile foundations. In effect, the cone penetrometer could be seen as a small pile, and its penetration through the ground as the plunge of a pile. Thus, in addition to estimation of su from cone resistance and use of the α method, pile shaft resistance can be estimated by direct correlation

Fundamentals of CONE PENETROMETER TEST (CPT) …

• The 60o tip of the cone forces a passive failure of the ground in front of the advancing tip. The instrumented tip senses soil resistance about 21cm (8.4 in) ahead of the advancing tip. • This means that the tip resistance reported as "undrained shear strength" is actually an average value, taken over the zone within 21 cm of the cone ...

What is a cone penetration test (CPT)?

A cone penetration test rig pushes a steel cone (about 32mm wide) into the ground, generally up to 20m below the surface or until the cone reaches a hard layer. The steel cone contains an electronic measuring system that records tip resistance and sleeve friction. As the cone is pushed into the ground, the soil responds
