What specific shear strength parameter for cohesive soils is directly determined from an Unconfined Compression Test (UCT)?

The specific shear strength parameter for cohesive soils that is directly determined from an Unconfined Compression Test (UCT) is the undrained shear strength (cu). The Unconfined Compression Test (UCT) is a laboratory procedure conducted on a cylindrical specimen of cohesive soil, such as clay, without any lateral confining pressure applied to its sides. The test involves applying a gradually increasing axial compressive load to the specimen until it fails, which is typically identified by a sudden decrease in ....
