SUMMARY
The discussion clarifies the differences between consolidated undrained and unconsolidated undrained tests in geotechnical engineering. In the consolidated undrained test, pore water pressure increases solely due to deviator stress application because drainage is allowed during the initial phase. Conversely, in the unconsolidated undrained test, both pore water pressure increases due to deviator stress (ud) and the sealed chamber pressure (uc) since drainage is not permitted. This distinction is critical for understanding soil behavior under stress conditions.
