It is special in case of triaxial Media. Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. The undrained shear strength (su) of a cohesive soil is equal to one-half the unconfined compressive strength (qu) when the soil is under the f =condition (f = the angle of internal friction) The unconfined co mpressive strength q u is related to the point load index withmm cores Isas follows Beside the diametral test, the axial test and the irregular lump test have also been proposed (see Figures 2b and 2c). The compressive load per unit area required to fail the specimen is called unconfined compressive strength of the soil. In the cone test, a cone with an angleis forced In this test, a cylindrical specimen of soil with aspect ratiowithout lateral support is tested to failure in simple compression, at a constant deformation rate (mm/min, mm/min, mm/min). UC test does not require the Various authors have compiled the values of the unconfined compressive strength for different rock types (Balmer, ; Johnson and DeGraff, ; Hatheway and Kiersch, Unconfined Compressive Strength (UCS) stands for the maximum axial compressive stress that a cohesive soil specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis The unconfined compression test is usually per-formed on a cylindrical sample with a diameter-to-length ratio of The sanple is compressed axially [Figure (a)] until failure occurs; the shear strength is taken as one-half the compressive strength. Strength anisotropy can also be assessed by using the point load Unconfined Compressive Strength, qu It is the load per unit area at which an uncon fined cylindrical specimen of soil will fail in compression test. iK\;OTEIf the axial compression force per unit area has not reached a maximum value even atpercent The undrained shear strength (su) of clays is commonly determined from an unconfined compression test.
