Determination of soil shear strength is essential for designing the foundation of structures, soil and soil retaining structures, soil slopes, etc., Shear strength of soil depends on various factors and insitu soil conditions. Therefore, when laboratory tests in soil are performed to evaluate shear strength of soil, the insitu soil conditions and other factors should be simulated for obtaining meaningful results. For example, the Unconsolidated Undrained test on soil will yield the undrained strength, which can be used for finding the immediate stability of an excavation
