10.7.6 Consolidated Undrained (CU) Compression Test
The purpose of a CU test is to determine the undrained and drained shear strength parameters (su, f9cs, f9p).
The CU test is conducted in a similar manner to the CD test except that after isotropic consolidation, the
axial load is increased under undrained condition and the excess porewater pressure is measured. The
applied stresses are as follows Read this topic
