The Unconsolidated Undrained Test (UU Test) is a laboratory procedure used to determine the shear strength of saturated soil without allowing drainage. In this test, a cylindrical soil sample is subjected to axial loading until failure occurs, while maintaining its natural moisture content. This method is particularly useful for assessing the behavior of cohesive soils, such as clay, under rapid loading conditions. The UU Test is commonly employed in geotechnical engineering to evaluate soil stability for construction projects. The results help engineers understand how soil will perform under undrained conditions, which is critical for designing foundations, slopes, and other structures in saturated environments.
