A t‐bar penetration test for soft clay that can be performed with existing cone penetration test (CPT) equipment is described. The results of the test can be directly related to the undrained shear strength of the clay via a plasticity solution, thus eliminating some of the uncertainty involved in the interpretation of conventional penetration tests in soft clay. Results from a field trial of the device are shown to compare favorably with the results of other in‐situ and laboratory strength tests.
